Epigenetics Chromatin. A related structure is present in the steroid hormone receptor family, although in this case, four cysteine residues coordinate the zinc ion and the finger is composed of two helices rather than one. In this study, a rice (Oryza sativa) functional homolog of LSD1, designated OsLSD1, was identified. Knockdown of these genes or treatment with DZnep resulted in decreased H3K27Me3 levels [91]. HHS 2021 Jan 5. doi: 10.1007/s00394-020-02454-3. Zinc finger proteins: new insights into structural and functional diversity John H Laity, Brian M Lee and Peter E Wright* protein (WT1) [9,10 ••] revealed that the linker is dynami-cally disordered in the free protein, but adopts a well-defined structure with restricted backbone flexibility upon binding to DNA. Their functions are extraordinarily diverse and include DNA recognition, RNA packaging, transcriptional activation, regulation of apoptosis, protein folding and assembly, and lipid binding. Zinc finger structures are as diverse as their functions. Zinc finger proteins are among the most abundant proteins in eukaryotic genomes. The artificial ZFP was capable of inhibiting gene transcription at the binding site. Combining 3–6 ZFP in a molecule, it can recognize and bind to a specific DNA into the genome. miR23a is correlated to shorter patient survival [143]. Novel zinc finger motifs are suggested to play important roles in gene regulation and chromatin remodeling. Zinc Finger Protein 618 Regulates the Function of UHRF2 (Ubiquitin-like with PHD and Ring Finger Domains 2) as a Specific 5-Hydroxymethylcytosine Reader J Biol Chem. The ZFN approach mix the features of ZFP specificity and add to this molecule a modified restriction enzyme FokI, with endonuclease feature; that is, as much the ZFP bind the specific region of DNA the FokI cleaves one strain of this DNA. Engineered DNA-binding molecules and their application to locus-specific epigenome editing. Their functions are extraordinarily diverse and include DNA recognition, RNA packaging, transcriptional activation, regulation of apoptosis, protein folding and assembly, and lipid binding. Since this seminal study, application of ZFPs to gene modifications has progressed significantly. Guo J, Luo C, Yang Y, Dong J, Guo Z, Yang J, Lian H, Ye C, Liu M. Cancer Manag Res. As improper folding of zinc finger domains is mostly associated with the loss of correct protein function, disruption of zinc finger structures may result in interference with manifold cellular processes involved in gene expression, growth regulation, and maintenance of the genomic integrity. The DNA-binding domains contain two zinc atoms, which are each held in place by four cysteine residues. Polymorphisms in this gene, especially rs1344706, are thought to confer increased susceptibility to schizophrenia, bipolar disorder, and heroin addiciton. This was also the case for patients with double or triple methylations in these genes compared to those with one or no methylation [140]. Zinc finger (Znf) domains are relatively small protein motifs which contain multiple finger-like protrusions that make tandem contacts with their target molecule. 2020 Nov 30;13(1):600. doi: 10.1186/s13071-020-04486-4. However, it has been found to encompass a wide variety of differing protein structures in eukaryotic cells. Amino Acid Composition in Various Types of Nucleic Acid-Binding Proteins. Although suppression may be effective, the inhibition may not be sufficiently durable for therapeutic use. May be involved in transcriptional regulation. (B–C) Locus-specific epigenome editing. Juxtaposition of the wild-type FokI monomers results in digestion of both target strands. Improvement in specificity of ZFNs has been achieved by making use of nuclease domains that function as obligate heterodimers [13] (Figure 3.2). Comparing MPM samples with normal pleura demonstrated a unique methylation profile. Epub 2010 May 11. Function i. Zinc finger proteins are among the most abundant proteins in eukaryotic genomes. Zinc (Zn) finger proteins are involved in many aspects of eukaryotic gene regulation and occur in proteins induced by differentiation and growth signals, in proto-oncogenes, in general TFs, and in regulatory genes of eukaryotic organisms (Caramori et al., 2019a). The first helix of each subunit fits into the major groove, and side chains from this helix make contacts with the edges of the base pairs. Functionally, these motifs carry out a wide variety of tasks within cells by providing stable structural scaffolds and driving critical binding interactions, especially among proteins, DNA, and RNA. It consists of ∼30 amino acids that may recognize three base pairs of DNA. 1993 May 25;268(15):11364-71. Toshitsugu Fujita, Hodaka Fujii, in Handbook of Epigenetics (Second Edition), 2017. A zinc finger is a small protein structural motif that is characterized by the coordination of one or more zinc ions in order to stabilize the fold. Asbestos can also change the epi-epigenome with methylation of p16, CDKN2B, and RASSF1 significantly associated with asbestos exposure [135]. Zinc finger protein (ZFP) is a common DNA binding domain found in many transcription factors. ZFNs have been generated by coupling DNA binding motifs of ZFPs, which comprise an engineered array of finger modules to the nickase of FokI. Biochemistry. Zinc finger proteins form a class of DNA-binding proteins that act as transcription factors by binding specifically to short DNA sequences and controlling the transcription of a number of genes. Function. Eur J Nutr. Biochemistry. Three genes were specifically methylated in MPM compared with AC of the lung: transmembrane protein 30B (TMEM30B), Kazal-type serine peptidase inhibitor domain 1 (KAZALD1), and mitogen-activated protein kinase 13 (MAPK13) [136]. Functional properties of zinc‐finger proteins. eCollection 2021. Mark Isalan, in Reference Module in Life Sciences, 2020. NX_O75312 - ZPR1 - Zinc finger protein ZPR1 - Function. Furthermore silencing of SOC was observed, which may have resulted in chronic activation of signal transducer and activator of transcription (STAT) further perpetuating the inflammatory phenotype. Binds DNA via its zinc fingers (PubMed:24821766). DNMT3B was significantly reduced in tumors with a concomitant increase in methylation of RASSF1 [135]. It is also common for the linker regions and zinc fingers to form stabilizing nonspecific contacts across the DNA minor groove. Zinc fingers may have evolved originally from peptides, which maintained a simple ββα structure (similar to that shown in Figure 1(b)) independently of zinc. Neurobiology of zinc and its role in neurogenesis. Would you like email updates of new search results? In this figure, single gRNA (sgRNA) is shown as gRNA. Epigenetic facilitators of stem cell pluripotency are the polycomb group (PcG) of proteins with EZH2 and EED being part of the polycomb repressor complex (PRC-2). Due to their diversity, it is difficult to come up with a simple definition of what unites all ZnF proteins; however, the most common approach is to define them as all small, functional domains that require coordination by at least one zinc ion (Laity et al., 2001) . These proteins bind nucleic acids and play important roles in various cellular functions, including cell proliferation, differentiation and apoptosis, and in regulating viral replication and transcription. hsa-miR-29c* analysis in MPM tumor tissues showed that its expression was an independent predictive factor for survival [145]. CRISPR/Cas consists of Cas9 and gRNA; gRNA determines recognition of a 23 bp target. The low level of this gene was associated with high levels of miR23a and miR27a. … Does not show transcription activity by itself, but regulates the transcription of downstream genes through interaction with other transcription factors (PubMed:21935722). Originally, nine novel consecutive repeats were found, each ~30 amino acids in length. In this study, a protein comprising three fingers was engineered to recognize a unique sequence of 9 bp occurring at the BCR-ABL fusion site that is commonly found in malignant cells of chronic myeloid leukemia.

Copyright © 2021 Elsevier B.V. or its licensors or contributors. Figure 9.2 outlines the association between epigenetic alterations and MPM. Resultant heterochromatin induction leads to potent transcriptional suppression, which may be sustained and effective over long ranges of DNA [18]. VP16 is a potent transcription activator and is essential for regulating expression of HSV genes [20]. Two subunits of a ZFN bind to opposite strands of a duplex, and a nick in each strand is generated such that a DSB is formed at the targeted DNA. Kumar V, Kumar A, Singh K, Avasthi K, Kim JJ. As detailed throughout the text, alterations in epigenetic modifiers such as HDACs and DNMT result in aberrant expression of many genes. The zinc atom is essential for DNA binding and the functioning of these TFs as mutation to remove zinc binding produces effects identical to gene deletion. 10.14B) is found in more than 600 human TFs.

Particularly promising is the rendering of CD4+ cells resistant to HIV infection after targeted mutation of the CCR5 gene by ZFNs [2].  |  By continuing you agree to the use of cookies. Here, we demonstrated that ZFP36L1 has an important role in host defense against influenza A virus (IAV) infection. DNMT1/DNMT3A/DNMT3B are all overexpressed in MPM and may contribute to carcinogenesis, as targeting these with antisense oligos result in MPM growth inhibition [134]. Steroid hormone receptors also contain a dimerization domain, allowing recognition of sequences with dyad symmetry (Fig. Zinc fingers are abundant in nature and the huge variety found in various organisms, from yeast to human, may in part be due to their modular nature. Epub 2010 May 18. Interacts with the SCR and MGP promoters (PubMed:21935722). Acts as a signaling molecule that communicates proliferative growth signals from the cytoplasm to the nucleus. Fusion of the type IIS restriction enzyme, FokI, has commonly been used to generate ZFNs and was first reported in 1996 [11]. genes encoding four different ZPT2-related proteins (AZF1, AZF2, AZF3, and STZ). This modular feature has also led to the development of engineered zinc finger DNA-binding proteins that can be tailored to bind specifically to alternative sequences of interest. ZF proteins fused with functional domains of FokI, an endonuclease, have been used as ZF-nucleases (ZFNs) to artificially introduce double-strand breaks in a sequence-specific manner [3,4]. MPM patients with methylation of TMS1 (target of methylation-induced silencing 1) or HIC-1 (hypermethylated in cancer 1) had significantly reduced overall survival [139]. Specific zinc-finger architecture required for HIV-1 nucleocapsid protein's nucleic acid chaperone function Mark C. Williams , Robert J. Gorelick , Karin Musier-Forsyth Proceedings of the National Academy of Sciences Jun 2002, 99 (13) 8614-8619; DOI: 10.1073/pnas.132128999 USA.gov. Please enable it to take advantage of the complete set of features! Rationale for the use of obligate heterodimers of FokI nuclease to improve cleavage specificity. To characterize the role of this type of protein, we analyzed the function of Arabidopsis L. Heynh. The length of the linker region between zinc fingers determines the number and spacing of the recognition helices docked in the DNA major groove. MiR-491-5p, as a Tumor Suppressor, Prevents Migration and Invasion of Breast Cancer by Targeting ZNF-703 to Regulate AKT/mTOR Pathway. This increase was associated with decreased survival. It was originally coined to describe the finger-like appearance of a hypothesized structure from the African clawed frog transcription factor IIIA. These proteins contain separate regions for hormone binding, DNA binding, and for transcriptional activation. Comparative transcriptomic analysis of antimony resistant and susceptible Leishmania infantum lines. Examples of these types of TFs include Sp1, the GATA family, and the Drosophila Kruppel gene. In an additional study, patients with low methylation profiles lived significantly longer compared with those with higher levels of methylated genes [136]. A TAL protein possesses a DNA-binding domain consisting of an assembly of DNA-binding modules; each module recognizes one nucleotide. DZNep treatment reduced tumor size by 50% and decreased H3K27Me3 levels within the RASSF1A, HIC-1, and p21 promoters. 2021 Jan 18;22(2):922. doi: 10.3390/ijms22020922. KRAB-containing zinc finger proteins (KRAB-ZFPs) contain both the KRAB domain and some zinc fingers and represent the largest single family of transcriptional regulators in mammals , .KRAB is found only in tetrapod vertebrates , and functions as a transcriptional repressor domain with its corepressor KRAB associated protein 1 (KAP1) , –. Furthermore, in a large cohort of MPM patient samples there were differences observed in the methylation frequencies in certain genes, some of which are also common in lung cancer. Organism. Lucas M. Chaible, ... Maria L. Zaidan Dagli, in Animal Models for the Study of Human Disease (Second Edition), 2017. Zinc finger structures are as diverse as their functions. Figure 42.1. High incidences of hypermethylation at the promoter region of E-cadherin and FHIT were observed at 71.4% and 78%, respectively [140]. Each ZF motif binds to a three-base sequence of double-helical DNA (Fig. Figure 3.2. The zinc finger protein sequence motif (Fig. Complementary electrostatic and hydrophobic interactions at the interface between nuclease domains, engineered by site-directed mutagenesis, favors formation of functional heterodimeric nucleases.

This section displays by default the canonical protein sequence and upon request all isoforms described in the entry. The first demonstration that it is possible to design ZFPs to bind to specific target sites was reported 20 years ago by Choo, Sanchez-Garcia, and Klug [10]. Other suppressor motifs have also been fused to ZFPs to achieve target gene suppression [15], but their use has not been as popular as that of KRAB. The DNA-binding region of these factors usually contains tandem repeats of the 30-residue zinc finger motif, Cys-X2/4-Cys-X12-His-X3–5-His. miR-34 is also dysregulated in MPM through promoter methylation silencing [144].

Adcock, in Reference Module in Biomedical Sciences, 2020. The methylation of MT1A was also correlated with asbestos burden [135,137]. It consists of ∼30 amino acids that may recognize three base pairs of DNA. In addition, new structural studies of proteins containing the classical Cys(2)His(2) zinc finger motif have led to novel insights into mechanisms of DNA binding and to a better understanding of their broader functions in transcriptional regulation. Online ahead of print. Characterized by an N-terminal KRAB domain and a C-terminal array of DNA-binding zinc fingers, they participate, together with their co-factor KAP1 (also known as TRIM28), in repression of sequences derived from transposable elements (TEs). Introduction. 2001 May 22;40(20):6093-101. doi: 10.1021/bi0025215. Rbm10 facilitates heterochromatin assembly via the Clr6 HDAC complex. It has long been known that direct binding of ZFPs to transcription regulatory elements is capable of impeding access by transcriptional factors to their regulatory elements [10]. In all cases, Zn2+ plays a structural role and does not interact directly with the DNA. In MPM, a number of these gene changes promote a chronic inflammatory state, a decrease in cell cycle inhibitors in addition to the promotion of anti-apoptotic mediators. Mammalian transcriptomes are CpG-poor, and ZAP may have evolved to exploit this feature to specifically target non-self viral RNA. The DNA-binding domains from the glucocorticoid receptor and the estrogen receptor form two perpendicular α-helices held together by hydrophobic interactions and folded into a globular domain. Zinc finger of the cerebellum (ZIC1), a possible TSG, is downregulated in MPM cell lines through promoter methylation [143]. Contribution of individual amino acids to the nucleic acid binding activities of the Xenopus zinc finger proteins TFIIIIA and p43. Simple worked examples of how to do this are explained here. Some of these domains bind zinc, but many do not; instead binding other metals such as iron, or no metal at all. 42.1A) [13]. NIH Arginine methylation of cellular nucleic acid binding protein (CNBP), a zinc finger protein, has shown to impede its ability to bind nucleic acids. Hamilton TB, Turner J, Barilla K, Romaniuk PJ. 2016 Jun 24;291(26):13679-88. doi: 10.1074/jbc.M116.717314. Of particular interest was HOXA9, which is involved in regulating some nuclear factor kappa B (NF-κB) responses [135]. Patrick Arbuthnot, in Gene Therapy for Viral Infections, 2015. This gene encodes a Kruppel-associated box (KRAB) zinc-finger protein, which belongs to a large group of transcriptional regulators in mammals. The most common zinc finger motif consists of a two-stranded anti-parallel β-sheet and a short α-helix (ββα) held together by a Zn2+ ion tetrahedrally coordinated by conserved cysteine and histidine residues in the α-helix and two β-strands (Figure 2(d)). Mus musculus (Mouse) Status. Plays a role for the localization and accumulation of the survival motor neuron protein SMN1 in sub-nuclear bodies, including gems and Cajal bodies. The expression of this miR is regulated through DNMTs [145]. Transcription factors often use zinc fingers to mediate protein–DNA interactions. The zinc finger motif was discovered in 1985 by Miller, McLachlan, and Klug in a protein responsible for controlling gene expression – the Xenopus transcription factor IIIA (TFIIIA).  |  In this regard, not only are zinc fingers independently folding structural building blocks, but they also are often encoded by single exons. Regions. The difference in methylation status between MPM and normal samples was an independent predictor of patient survival [135]. COVID-19 is an emerging, rapidly evolving situation. This results in finger-like structures that project from the surface of the protein. Zinc-Finger Protein. ZF proteins contain ZF motif(s), which consist of about 30 amino acid residues (a.a.). The human gene maps to chromosome 2 q32.1 and consists of 4 exons that code for a protein of 1210 amino acids (137 kDa). The KRAB domain is naturally found in ZFPs that perform transcription inhibition in tetrapods [16]. [provided by RefSeq, Nov 2015] For locus-tagging without DNA cleavage, a catalytically inactive form of Cas9 (dCas9) is used instead of wild-type Cas9. Krüppel-associated box domain zinc finger proteins (KRAB-ZFPs) are the largest family of transcriptional regulators in higher vertebrates. 10.14C). The expression of OsLSD1 was light-induced or dark-suppressed. Currently, there is a wealth of information on the topic, and engineered derivatives of ZFPs are now at advanced stages of development for clinical use. EZH2 was overexpressed in MPM patient samples compared with normal pleura [141]. 2014 May;27(5):446-60. doi: 10.1094/MPMI-09-13-0271-R. The use of multiple zinc finger motifs in a single DNA-binding module allows for recognition of an extended (and therefore more specific) DNA sequence, since each finger can in principle recognize a base-pair triplet. In zinc fingers, the role of zinc is structural and zinc ions typically do not participate in the function directly. Pleiotropic function of the putative zinc-finger protein MoMsn2 in Magnaporthe oryzae Mol Plant Microbe Interact. Xenopus laevis TFIIIA … Little is known about the characteristics and function of the encoded protein. The proteins encoded by nese52 and nele49 contain four C2H2 zinc-finger domains and share an amino acid identity of 35.6%. Surprisingly, however, bacteria do not appear to take advantage of these little structures. This gene product belongs to the zinc finger protein superfamily, members of which are regulatory proteins characterized by nucleic acid-binding zinc finger domains. Reexpression of miR-34a/b through DAC treatment resulted in cellular arrest, and the reduction of migration and invasion in an MPM cell line [144]. Here, we report that arsenite binds to both CCHC DNA-binding zinc fingers of the DNA repair protein PARP-1 (poly(ADP-ribose) polymerase-1). Engineered zinc fingers have numerous applications in both biotechnology and medicine. Mapping regions of yeast transcription factor IIIA required for DNA binding, interaction with transcription factor IIIC, and transcription activity. The glucocorticoid receptor binds as a dimer. In addition, WNT inhibitory factor 1 (WIF-1) and serum response factor (SFR (1, 2, 4)) promoter methylation was observed in a high number of mesothelioma tissue samples [138]. (A) Engineered DNA-binding molecules. The link between epigenetic alterations and MPM. Zinc fingers are extremely versatile, as can be seen by their abundance in nature: over 700 proteins contain Cys2–His2 zinc fingers in the human genome alone and they are thought to be the largest protein superfamily in metazoans. As with the natural FokI enzyme, ZFNs are engineered to form dimers. A zinc finger (ZF) protein consists of ZF motifs; one motif recognizes three bases. 2021 Jan 19;14(1):8. doi: 10.1186/s13072-021-00382-y. Values of between 14% and 20% were determined for APC1A, RASSF1A, and DAPK; and values of 28–55% for p16, APC1B, p14, and RARβ (55.8%) [140]. Zinc finger protein (ZFP) is a common DNA binding domain found in many transcription factors. Importantly, chains of artificial zinc fingers may be designed to bind novel DNA sequences following a code. The human zinc finger antiviral protein (ZAP) recognizes RNA by binding to CpG dinucleotides. In these proteins, termed zinc fingers, a short chain of 20-30 amino acids is enough to create a solid, stable structure. The discovery of zinc fingers and their development for practical applications in gene regulation and genome manipulation. Overexpression of ZFP36L1 reduced IAV replication via translational repression of HA, M … H3K27Me3 levels within the promoters of RASSFIA and HIC-1 were markedly decreased in cells exhibiting knockdown of EZH2 or EED [141]. Repeated cleavage and error-prone repair by NHEJ leads to site-specific mutation. Andrade JM, Gonçalves LO, Liarte DB, Lima DA, Guimarães FG, de Melo Resende D, Santi AMM, de Oliveira LM, Velloso JPL, Delfino RG, Pescher P, Späth GF, Ruiz JC, Murta SMF. The ZFN approach mix the features of ZFP specificity and add to this molecule a modified restriction enzyme FokI, with … GAS5 is reduced in MPM cell lines compared with normal mesothelial cells and is associated with cell cycle length [147].

Other genes that are significantly changed through methylation are ESR1 (estrogen receptor 1), SLC6A20 (solute carrier family 6), and SYK (spleen tyrosine kinase) [137]. Zinc finger protein 27. As a type IIS restriction enzyme, cleavage and DNA recognition sites of FokI are distinct. Anne-Marie Baird, ... Steven G. Gray, in Epigenetic Cancer Therapy, 2015. In any case, the ββα fold is one of the smallest possible units of protein tertiary structure, and may therefore be one of the oldest. ZFPs and their derivatives have been the subject of research performed over a long period of time. The motifs are particularly important in gene regulation, where many proteins employ them to bind DNA in a sequence-specific manner, to activate or inhibit particular genes.
