Ubiquitin-conjugating enzyme E2 R2

UniProtKB accession:  Q712K3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  E2 ubiquitin-conjugating enzyme that accepts ubiquitin from an E1 ubiquitin-activating protein, and catalyzes its covalent attachment to other proteins by an E3 ubiquitin-protein ligase complex (PubMed:12037680, PubMed:20061386, PubMed:38326650). In vitro catalyzes monoubiquitination and 'Lys-48'-linked polyubiquitination (PubMed:12037680, PubMed:20061386, PubMed:38326650). Works in collaboration with various Cul1-RING and Cul2-RING E3 ligase complexes (PubMed:38326650). May be involved in degradation of katenin (PubMed:12037680).
