CC   -!- FUNCTION: Catalyzes the covalent attachment of ubiquitin to other
CC       proteins. Functions in degradation of misfolded or regulated proteins
CC       localized in the endoplasmic reticulum (ER) lumen or membrane via the
CC       ubiquitin-proteasome system. Cognate E2 conjugating enzyme for the
CC       doa10 ubiquitin ligase complex, which is part of the ERAD-C pathway
CC       responsible for the rapid degradation of membrane proteins with
CC       misfolded cytoplasmic domains. {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-L-cysteine +
CC         [E2 ubiquitin-conjugating enzyme]-L-cysteine = [E1 ubiquitin-
CC         activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-
CC         conjugating enzyme]-L-cysteine.; EC=2.3.2.23;
CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU00388};
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:Q5VVX9}.
CC   -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00388}.
