UniProt ID: A9JRZ0
FUNCTION: E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. {ECO:0000250}.
CATALYTIC ACTIVITY: Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L- cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin- conjugating enzyme]-L-cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.; EC=2.3.2.26; Evidence={ECO:0000250|UniProtKB:Q9HCE7};
PATHWAY: Protein modification; protein ubiquitination.
SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}. Cell membrane {ECO:0000250}. Membrane raft {ECO:0000250}.
