CC -!- FUNCTION: Might act as an E3 ubiquitin-protein ligase, or as part of E3
CC complex, which accepts ubiquitin from specific E2 ubiquitin-conjugating
CC enzymes and then transfers it to substrates.
CC {ECO:0000256|ARBA:ARBA00003976}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[E2 ubiquitin-conjugating enzyme]-S-ubiquitinyl-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + [acceptor protein]-N(6)-ubiquitinyl-L-lysine.;
CC EC=2.3.2.31; Evidence={ECO:0000256|ARBA:ARBA00001798};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|ARBA:ARBA00001947};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000256|ARBA:ARBA00004906}.
CC -!- SIMILARITY: Belongs to the RBR family. Ariadne subfamily.
CC {ECO:0000256|ARBA:ARBA00005884}.
