CC -!- FUNCTION: E3 ubiquitin-protein ligase that mediates ubiquitination and
CC subsequent proteasomal degradation of target proteins. E3 ubiquitin
CC ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the
CC form of a thioester and then directly transfers the ubiquitin to
CC targeted substrates. {ECO:0000256|RuleBase:RU201113}.
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; Evidence={ECO:0000256|ARBA:ARBA00000900,
CC ECO:0000256|RuleBase:RU201113};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000256|ARBA:ARBA00004906, ECO:0000256|RuleBase:RU201113}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC Nucleus {ECO:0000256|ARBA:ARBA00004123}.
CC -!- DOMAIN: The RING-type zinc finger domain is essential for ubiquitin
CC ligase activity. {ECO:0000256|RuleBase:RU201113}.
CC -!- DOMAIN: The SBD domain (substrate-binding domain) mediates the
CC interaction with substrate proteins. It is related to the TRAF family.
CC {ECO:0000256|RuleBase:RU201113}.
CC -!- SIMILARITY: Belongs to the SINA (Seven in absentia) family.
CC {ECO:0000256|ARBA:ARBA00009119, ECO:0000256|RuleBase:RU201113}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
