protein MRG1 isoform X2 [Cucumis melo]

Protein Classification

MRG family protein( domain architecture ID 13040224)

MRG (MORF4 related gene) family protein similar to human mortality factor 4-like protein 1, also called MORF-related gene 15 protein (MRG15), and Schizosaccharomyces pombe chromatin modification-related protein eaf3, both of which are components of the NuA4 histone acetyltransferase complex that is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histone H4 and H2A

MRG; This family consists of three different eukaryotic proteins (mortality factor 4 (MORF4/MRG15), male-specific lethal 3(MSL-3) and ESA1-associated factor 3(EAF3)). It is thought that the MRG family is involved in transcriptional regulation via histone acetylation. It contains 2 chromo domains and a leucine zipper motif.

 32-87 3.06e-25

chromo barrel domain of human male-specific lethal complex subunit 3, and similar proteins; This subgroup includes human male-specific lethal (MSL) complex subunit 3 (MSL3, also known as MSL3L1). The MSL3 chromodomain specifically recognizes the H4K20 monomethyl mark, in a DNA-dependent manner, and may be involved in chromosomal targeting of the MSL complex. Also included is MORF-related gene on chromosome 15 (MRG15, also known as MORF4L1) which specifically binds to Lys36-methylated histone H3 and plays a role in transcriptional regulation and in DNA repair. This subgroup also includes Arabidopsis thaliana Morf Related Gene 2 (MRG2) which acts as a H3K4me3/H3K36me3 reader involved in the regulation of Arabidopsis flowering. 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 chromo domain.

 41-77 7.69e-08

malignant brain tumor (MBT) repeat found in PHD finger protein 20-like protein 1 (PHF20L1) and similar domains; PHF20L1 associates with SOX2, antagonizes SOX2 ubiquitination and the sequential degradation induced by MLL1/WDR5 complexes. It binds both monomethylated Lys-42 and Lys-117 in SOX2 and thereby prevents SOX2 proteolysis. PHF20L1 also reads and controls enzyme levels of methylated DNMT1 in cells, thus representing a novel antagonist of DNMT1 degradation. PHF20L1 contains one MBT (malignant brain tumor) repeat. The MBT repeat is a protein module that recognizes methylated lysine residues on histones. MBT repeats contain a semi-aromatic cage to accommodate methyllysine and show specificity towards the lower methylation states of lysine. This model corresponds to the MBT repeat of PHF20L1 and similar domains that contains the semi-aromatic cage that may bind methylated lysine residues.

 41-80 2.73e-07

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.
