The function of Ensembl gene identifier ENSG00000170035 (UBE2E3, ubiquitin conjugating enzyme E2 E3) is as follows. Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-11'- and 'Lys-48'-, as well as 'Lys-63'-linked polyubiquitination. Participates in the regulation of transepithelial sodium transport in renal cells. {ECO:0000269|PubMed:10343118, ECO:0000269|PubMed:20061386, ECO:0000269|PubMed:27237050}.
