DESCRIPTION

Also known as DNM3A_HUMAN, DNMT3A. Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development (PubMed:12138111, PubMed:16357870, PubMed:30478443). DNA methylation is coordinated with methylation of histones (PubMed:12138111, PubMed:16357870, PubMed:30478443). It modifies DNA in a non-processive manner and also methylates non-CpG sites (PubMed:12138111, PubMed:16357870, PubMed:30478443). May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1 (By similarity). Plays a role in paternal and maternal imprinting (By similarity). Required for methylation of most imprinted loci in germ cells (By similarity). Acts as a transcriptional corepressor for ZBTB18 (By similarity). Recruited to trimethylated 'Lys-36' of histone H3 (H3K36me3) sites (By similarity). Can actively repress transcription through the recruitment of HDAC activity (By similarity). Also has weak auto-methylation activity on Cys-710 in absence of DNA (By similarity). Heterotetramer composed of 1 DNMT3A homodimer and 2 DNMT3L subunits (DNMT3L-DNMT3A-DNMT3A-DNMT3L) (PubMed:17713477, PubMed:19834512). Interacts with UBC9, PIAS1 and PIAS2 (By similarity). Binds the ZBTB18 transcriptional repressor (By similarity). Interacts with SETDB1 (PubMed:16682412). Associates with HDAC1 through its ADD domain (By similarity). Interacts with UHRF1 (By similarity). Interacts with DNMT1 and DNMT3B (PubMed:12145218). Interacts with the PRC2/EED-EZH2 complex (PubMed:16357870). Interacts with MPHOSPH8 (PubMed:20871592, PubMed:22086334). Interacts with histone H3 that is not methylated at 'Lys-4' (H3K4) (By similarity). Interacts with SPOCD1 (By similarity). Interacts with ZNF263; recruited to the SIX3 promoter along with other proteins involved in chromatin modification and transcriptional corepression where it contributes to transcriptional repression (PubMed:32051553).
