DESCRIPTION

Also known as MTF2_MOUSE, Mtf2, Pcl2. Polycomb group (PcG) protein that specifically binds histone H3 trimethylated at 'Lys-36' (H3K36me3) and recruits the PRC2 complex, thus enhancing PRC2 H3K27me3 methylation activity (PubMed:20144788, PubMed:21367819, PubMed:21059868, PubMed:23104054, PubMed:22438827). Regulates the transcriptional networks during embryonic stem cell self-renewal and differentiation (PubMed:20144788). Promotes recruitment of the PRC2 complex to the inactive X chromosome in differentiating XX ES cells and PRC2 recruitment to target genes in undifferentiated ES cells (PubMed:21367819). Required to repress Hox genes by enhancing H3K27me3 methylation of the PRC2 complex (PubMed:21059868). In some conditions may act as an inhibitor of PRC2 activity: able to activate the CDKN2A gene and promote cellular senescence by suppressing the catalytic activity of the PRC2 complex locally (PubMed:21059868). Binds to the metal-regulating-element (MRE) of MT1A gene promoter (PubMed:7772254). Associates with the PRC2 complex, which consists of the core components EED, EZH1 or EZH2, SUZ12, and RBBP4, and various combinations of accessory subunits including AEBP2, JARID2, PHF19, MTF2 and EPOP (PubMed:21367819, PubMed:22438827). Forms a dimeric PRC2.1 (class 1, PRC-PCL) complex consisting of at least SUZ12, RBBP4, and PHF19 or MTF2; PHF19 and MTF2 stabilize the dimeric structure which enhances PRC2 interaction with chromatin (By similarity).
