Histone-lysine N-methyltransferase, H3 lysine-4 specific

UniProtKB accession:  P38827

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalytic component of the COMPASS (Set1C) complex that specifically mono-, di- and trimethylates histone H3 to form H3K4me1/2/3 (PubMed:11742990, PubMed:11751634, PubMed:11818070, PubMed:11805083, PubMed:12353038, PubMed:11752412, PubMed:12060701, PubMed:14636589, PubMed:12845608, PubMed:15949446, PubMed:29071121). Binds RNAs involved in chromosome segregation, splicing and transcriptional regulation; appears to bind transcripts both co- and post-transcriptionally and binding might negatively affect its histone methyltransferase activity (PubMed:29071121, PubMed:16787775). COMPASS recognizes ubiquitinated H2B on one face of the nucleosome which stimulates the methylation of H3 on the opposing face (PubMed:31922488). Plays a role in telomere length maintenance and transcription elongation regulation (PubMed:9398665, PubMed:9988274, PubMed:11742990, PubMed:11751634, PubMed:11818070, PubMed:11805083, PubMed:14636589, PubMed:15949446).
