Name Ubiquitin-conjugating enzyme E2 A
Synonyms
  1. HR6A
  2. RAD6 homolog A
  3. Ubiquitin carrier protein A
  4. Ubiquitin-protein ligase A
  5. hHR6A
Gene Name UBE2A
Protein Type Enzyme
Biological Properties
General Function Involved in acid-amino acid ligase activity
Specific 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.
