RL Submitted (OCT-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: E3 ubiquitin-protein ligase which may be involved in
CC endosomal trafficking. E3 ubiquitin ligases accept ubiquitin from an E2
CC ubiquitin-conjugating enzyme in the form of a thioester and then
CC directly transfer the ubiquitin to targeted substrates. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27;
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass
CC membrane protein. Lysosome membrane; Multi-pass membrane protein.
CC Endosome membrane {ECO:0000250}; Multi-pass membrane protein
CC {ECO:0000250}.
CC -!- DOMAIN: The RING-CH-type zinc finger domain is required for E3 ligase
CC activity. {ECO:0000255|PROSITE-ProRule:PRU00623}.
