7-62 8.61e-30

chromodomain of chromobox homolog 7; CHRomatin Organization Modifier (chromo) domain of chromobox homolog 7 (CBX7), a component of the PcG repressive complex PRC1, one of the two classes of PRCs. PcG proteins form large multiprotein complexes (PcG bodies) which are involved in the stable repression of genes involved in development, signaling or cancer via chromatin-based epigenetic modifications. Mammalian PRC1 includes canonical (cPRC1) and non-canonical complexes; cPRC1, contains four core subunits including one CBX protein (CBX2, CBX4, and CBX6-CBX8) that binds H3K27me3. CBX family members have different affinity for H3K27me3, with CBX7 having the highest binding capability. The human CBX proteins show distinct nuclear localizations and contribute differently to transcriptional repression. Some CBX proteins of the PRC1 complex have been implicated in transcriptional activation as well as in PRC1-independent roles in embryonic stem cells and in somatic cells. CBX proteins may act as an oncogene or tumor suppressor in a cell-type-dependent manner, for example CBX8 promotes proliferation while suppressing metastasis, in colorectal carcinoma progression. CBX7 has been shown to function as a tumor suppressor in lung carcinoma and an oncogene in gastric cancer and lymphoma.

chromodomain of chromobox homolog 4; CHRomatin Organization Modifier (chromo) domain of chromobox homolog 4 (CBX4), a component of the PcG repressive complex PRC1, one of the two classes of PRCs. PcG proteins form large multiprotein complexes (PcG bodies) which are involved in the stable repression of genes involved in development, signaling or cancer via chromatin-based epigenetic modifications. Mammalian PRC1 includes canonical (cPRC1) and non-canonical complexes; cPRC1, contains four core subunits including one CBX protein (CBX2, CBX4, and CBX6-CBX8) that binds H3K27me3. CBX family members have different affinity for H3K27me3, with CBX7 having the highest binding capability. The human CBX proteins show distinct nuclear localizations and contribute differently to transcriptional repression. Some CBX proteins of the PRC1 complex have been implicated in transcriptional activation as well as in PRC1-independent roles in embryonic stem cells and in somatic cells. In addition to a chromodomain with H3K27me3-binding activity, Cbx4 contains two SUMO-interacting motifs responsible for its small ubiquitin-related modifier (SUMO) E3 ligase activity. CBX proteins may act as an oncogene or tumor suppressor in a cell-type-dependent manner, for example CBX8 promotes proliferation while suppressing metastasis, in colorectal carcinoma progression. CBX4 may serve as a tumor suppressor in colorectal carcinoma, and has been shown to be an oncogene in osteosarcoma and breast cancer.

11-59 1.78e-18

CHROMO (CHRromatin Organization Modifier) domains and chromo shadow domains; Members of this group are chromodomains or chromo shadow domains; these are SH3-fold-beta-barrel domains of the chromo-like superfamily. Chromodomains lack the first strand of the SH3-fold-beta-barrel, this first strand is altered by insertion in the chromo shadow domains. The chromodomain is a conserved region of about 50 amino acids, found in a variety of chromosomal proteins, and which appears to play a role in the functional organization of the eukaryotic nucleus. The chromodomain is implicated in the binding, of the proteins in which it is found, to methylated histone tails and maybe RNA. Chromodomain-containing proteins include: i) those having an N-terminal chromodomain followed by a related chromo shadow domain, such as Drosophila and human heterochromatin protein Su(var)205 (HP1), and mammalian modifier 1 and 2; ii) those having a single chromodomain, such as Drosophila protein Polycomb (Pc), mammalian modifier 3, human Mi-2 autoantigen, and several yeast and Caenorhabditis elegans proteins of unknown function; iii) those having paired tandem chromodomains, such as mammalian DNA-binding/helicase proteins CHD-1 to CHD-4 and yeast protein CHD1; (iv) and elongation factor eEF3, a member of the ATP-binding cassette (ABC) family of proteins, that serves an essential function in the translation cycle of fungi. eEF3 is a soluble factor lacking a transmembrane domain and having two ABC domains arranged in tandem, with a unique chromodomain inserted within the ABC2 domain.

11-59 1.52e-13

chromodomain of heterochromatin protein 1 proteins, including HP1alpha, HP1beta, and HP1gamma; CHRomatin Organization Modifier (chromo) domain of mammalian HP1alpha (Cbx5), HP1beta (Cbx1), HP1gamma (Cbx5), and similar proteins. HP1 has diverse functions in heterochromatin formation and impacts both gene expression and gene silencing. HP1 has two conserved protein-protein interaction domains, a single N-terminal chromodomain (CD) which can bind to histone proteins via methylated lysine residues, and a related C-terminal chromo shadow domain (CSD) which is responsible for the homodimerization and interaction with a number of chromatin-associated non-histone proteins; a flexible hinge region separates the CD and CSD and may bind nucleic acid. HP1 is a highly conserved non-histone chromosomal protein that is evolutionarily conserved from fission yeast to plants and animals. There are three human homologs of HP1 proteins: HP1alpha (also known as Cbx5), HP1beta (also known as Cbx1), and HP1gamma (also known as Cbx3).

chromodomain of insect HP1a; CHRomatin Organization Modifier (chromo) domain of insect HP1a. HP1a is a member of the heterochromatin protein family, and is enriched in the heterochromatin and associated with centromeres. HP1 has diverse functions in heterochromatin formation and impacts both gene expression and gene silencing. HP1 has two conserved protein-protein interaction domains, a single N-terminal chromodomain (CD) which can bind to histone proteins via methylated lysine residues, and a related C-terminal chromo shadow domain (CSD) which is responsible for the homodimerization and interaction with a number of chromatin-associated non-histone proteins; a flexible hinge region separates the CD and CSD and may bind nucleic acid. HP1 is a highly conserved non-histone chromosomal protein that is evolutionarily conserved from fission yeast to plants and animals. In Drosophila, there are at least five HP1 family proteins, this subgroup includes the CD of Drosophila melanogaster HP1a.

chromodomain of Drosophila melanogaster Rhino, and similar proteins; N-terminal CHRomatin Organization Modifier (chromo) domain of Drosophila melanogaster Rhino (also known as heterochromatin protein 1-like), and similar proteins. Rhino is a female-specific protein that affects chromosome structure and egg polarity that is required for germline PIWI-interacting RNA (piRNA) production. In Drosophila the RDC (rhino, deadlock, and cutoff) complex, composed of rhino, the protein deadlock (Del) and the Rai1-like transcription termination cofactor cutoff (Cuff) binds to chromatin of dual-strand piRNA clusters, special genomic regions, which encode piRNA precursors. The RDC complex is anchored to H3K9me3-marked chromatin in part via the H3K9me3-binding activity of Rhino, and is required for transcription of piRNA precursors. A chromodomain is a conserved region of about 50 amino acids, found in a variety of chromosomal proteins, and which appears to play a role in the functional organization of the eukaryotic nucleus. The chromodomain is implicated in the binding, of the proteins in which it is found, to methylated histone tails and maybe RNA.

10-58 6.66e-08

chromodomain of heterochromatin protein 1 proteins, including HP1alpha, HP1beta, and HP1gamma; uncharacterized subgroup; CHRomatin Organization Modifier (chromo) domain of mammalian HP1alpha (Cbx5), HP1beta (Cbx1), HP1gamma (Cbx5), and similar proteins. HP1 has diverse functions in heterochromatin formation and impacts both gene expression and gene silencing. HP1 has two conserved protein-protein interaction domains, a single N-terminal chromodomain (CD) which can bind to histone proteins via methylated lysine residues, and a related C-terminal chromo shadow domain (CSD) which is responsible for the homodimerization and interaction with a number of chromatin-associated non-histone proteins; a flexible hinge region separates the CD and CSD and may bind nucleic acid. HP1 is a highly conserved non-histone chromosomal protein that is evolutionarily conserved from fission yeast to plants and animals. There are three human homologs of HP1 proteins: HP1alpha (also known as Cbx5), HP1beta (also known as Cbx1), and HP1gamma (also known as Cbx3).

CHROMO (CHRromatin Organization Modifier) domain; uncharacterized subgroup; The chromodomain is a conserved region of about 50 amino acids, found in a variety of chromosomal proteins. The chromodomain is implicated in the binding, of the proteins in which it is found, to methylated histone tails and maybe RNA. A chromodomain may occur as a single instance, in a tandem arrangement, or followed by a related chromo shadow domain. Chromodomains belong to the chromo-like superfamily of SH3-fold-beta-barrel domains which includes chromo shadow domains and chromo barrel domains. Chromodomains differ from these in that they lack the first strand of the SH3-fold-beta-barrel. This first strand is altered by insertion in the chromo shadow domains, and chromo barrel domains are typical SH3-fold-beta-barrel domains with sequence similarity to the canonical chromo domain.

11-57 8.45e-08

chromodomain of histone methyltransferase SUV39H1, and similar proteins; CHRomatin Organization Modifier (chromo) domain of human SUV39H1, a histone lysine methyltransferase (HMT) which catalyzes di- and tri-methylation of lysine 9 of histone H3 (H3K9me2/3), leading to heterochromatin formation and gene silencing. H3K9me2/3 represents a specific mark for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3, and/or CBX5) proteins to methylated histones. SUV39H1 mainly functions in heterochromatin regions. The human SUV39H1/2, histone H3K9 methyltransferases, are the mammalian homologs of Drosophila Su(var)3-9 and Schizosaccharomyces pombe Clr4. SUV39H1 contains a chromodomain at its N-terminus and a SET domain at its C-terminus. Although the SET domain performs the catalytic activity, the chromodomain of SUV39H1 is essential for the catalytic activity of SUV39H1. A chromodomain is a conserved region of about 50 amino acids, found in a variety of chromosomal proteins, and which appears to play a role in the functional organization of the eukaryotic nucleus. The chromodomain is implicated in the binding, of the proteins in which it is found, to methylated histone tails and maybe RNA. A chromodomain may occur as a single instance, in a tandem arrangement, or followed by a related chromo shadow domain.

10-49 8.80e-08

chromodomain of the Chromodomain Y-like protein family; This group includes the chromodomain found in the mammalian chromodomain Y-like (CDY) protein family, and similar proteins. The human CDY family includes 6 proteins: the genes encoding four of these: two copies of CDY1 (CDY1a, CDY1a) and two copies of CDY2(CDY2a and CDY2b), are located on chromosome Y, and the genes encoding the other two members (CDYL and CDYL2) are located on autosomes. The chromosomal genes are only present in primates, whereas the CDYL and CDYL2 genes exist in most mammalian species. The CDY family proteins contain two functional domains: a chromodomain involved in chromatin binding and a catalytic domain found in many coenzyme A (CoA)- dependent acylation enzymes. CDYL is ubiquitously expressed, whereas CDYL2 shows selective expression in tissues of testis, prostate, spleen, and leukocyte. The CDYL genes are ubiquitously expressed, the CDY genes are only expressed in the testis. Deletion of the CDY1b gene has been shown to be a risk factor for male infertility. Impairments in CDY2 expression could be implicated in the pathogenesis of maturation arrest (a failure of germ cell development).

13-61 1.70e-03

chromodomain-like insertion in an ATPase domain of elongation factor eEF3; Eukaryotic elongation factor eEF3 (also known as EF-3, YEF3, and TEF3), a member of the ATP-binding cassette (ABC) family of proteins, is a ribosomal binding ATPase essential for fungal translation machinery. Until recently it was considered fungal-specific and therefore an attractive target for antifungal therapy; however, recent bioinformatics analysis indicates it may be more widely distributed among other unicellular eukaryotes, and translation elongation factor 3 activity has been demonstrated from a non-fungal species, Phytophthora infestans. eEF3 is a soluble factor lacking a transmembrane domain and having two ABC domains arranged in tandem, with a unique chromodomain inserted within the ABC2 domain. Chromodomain mutations in the ABC2 domain of eEF3 have been shown to reduce ATPase activity, but not ribosome binding. Thus, the chromodomain-like insertion is critical to eEF3 function. In addition to its elongation function, eEF3 has been shown to interact with mRNA in a translation independent manner, suggesting an additional, non-elongation function for this factor.

11-56 7.02e-03

N-terminal chromodomain of the fission yeast histone methyltransferase Clr4, and similar proteins; N-terminal CHRomatin Organization Modifier (chromo) domain of cryptic loci regulator 4 (Clr4), a histone H3 lysine methyltransferase which targets H3K9. Clr4 regulates silencing and switching at the mating-type loci and affects chromatin structure at centromeres. Clr4 is a catalytic component of the rik1-associated E3 ubiquitin ligase complex that shows ubiquitin ligase activity and is required for histone H3K9 methylation. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting swi6/HP1 to methylated histones which leads to transcriptional silencing within centromeric heterochromatin, telomeric regions and at the silent mating-type loci. A chromodomain is a conserved region of about 50 amino acids, found in a variety of chromosomal proteins, and which appears to play a role in the functional organization of the eukaryotic nucleus. The chromodomain is implicated in the binding, of the proteins in which it is found, to methylated histone tails and maybe RNA. A chromodomain may occur as a single instance, in a tandem arrangement, or followed by a related chromo shadow domain.

chromodomain 2 of chloroplast signal recognition particle 43 kDa protein, and similar proteins; This subgroup includes the chromodomain 2 of chloroplast SRP43 (cpSRP43), and similar proteins. CpSRP43 is a component of the chloroplast signal recognition particle (SRP) pathway. It forms a stable complex with cpSRP54 (cpSRP complex) which is required for the efficient posttranslational transport of members of the nuclearly encoded light harvesting chlorophyll-a/b-binding proteins (LHCPs) to the thylakoid membrane. Chromatin organization modifier (chromo) domain is a conserved region of around 50 amino acids found in a variety of chromosomal proteins, which appear to play a role in the functional organization of the eukaryotic nucleus. Experimental evidence implicates the chromodomain in the binding activity of these proteins to methylated histone tails and maybe RNA. May occur as single instance, in a tandem arrangement or followed by a related chromo shadow domain.

chromo barrel domain of retinoblastoma binding protein 1, and similar proteins; ...
15-51 9.57e-03

chromo barrel domain of retinoblastoma binding protein 1, and similar proteins; Retinoblastoma-binding protein 1 (RBP1), also termed AT-rich interaction domain 4A, is a ubiquitously expressed nuclear protein. RBP1 is a tumor and leukemia suppressor that binds both methylated histone tails and DNA, and is involved in epigenetic regulation in leukemia and Prader-Willi/Angelman syndromes. The chromo barrel domain of RBP1 has been reported to recognize histone H4K20me3 weakly, and this binding is enhanced by the simultaneous binding of DNA. RBP1 binds directly, with several other proteins, to retinoblastoma protein (pRB) which regulates cell proliferation; pRB represses transcription by recruiting RBP1. SH3-fold-beta-barrel domains of the chromo-like superfamily include chromodomains, chromo shadow domains, and chromo barrel domains, and are implicated in the recognition of lysine-methylated histone tails and nucleic acids. The chromodomain differs, in that it lacks the first strand of the SH3-fold-beta-barrel. This first strand is altered by insertion in the chromo shadow domains, and chromo barrel domains are typical SH3-fold-beta-barrel domains with sequence similarity to the canonical chromodomain.
