Protein Information (annotations from UniProt)

Database IDHIV0007705
UniProt IDP49459
Primary gene name(s)UBE2A
Synonym gene name(s)RAD6A
Protein nameUbiquitin-conjugating enzyme E2 A
Protein functionAccepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In association with the E3 enzyme BRE1, RNF20 and/or RNF40, it plays a role in transcription regulation by catalyzing the monoubiquitination of histone H2B at 'Lys-120' to form H2BK120ub1. H2BK120ub1 gives a specific tag for epigenetic transcriptional activation, elongation by RNA polymerase II, telomeric silencing, and is also a prerequisite for H3K4me and H3K79me formation. In vitro catalyzes 'Lys-11', as well as 'Lys-48'-linked polyubiquitination. Required for postreplication repair of UV-damaged DNA. {ECO:0000269|PubMed:16337599, ECO:0000269|PubMed:20061386}.
