Human UBE2A, recombinant (N-GST, 6His)

Recombinant Human Ubiquitin-Conjugating Enzyme E2 A is produced by our E.coli expression system and the target gene encoding Met1-Cys152 is expressed with a GST, 6His tag at the N-terminus. Protein function: Accepts 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. [The UniProt Consortium]
