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. It probably triggers the ubiquitin-mediated
CC degradation of different 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 -!- DOMAIN: The RING-type zinc finger domain is essential for ubiquitin
CC ligase activity. {ECO:0000250}.
CC -!- DOMAIN: The SBD domain (substrate-binding domain) mediates the
CC homodimerization and the interaction with substrate proteins. It is
CC related to the TRAF family. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the SINA (Seven in absentia) family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AED94245.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=BAB09036.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
