Ubiquitin-conjugating enzyme E2 G1 (UBE2G1)

Accepts ubiquitin in the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys- 48'-, as well as 'Lys-63'-linked polyubiquitination.

May be involved in degradation of muscle-specific proteins. Mediates polyubiquitination of CYP3A4.
