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. {ECO:0000250,
CC ECO:0000269|PubMed:12446796}.
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:0000250|UniProtKB:Q9Y4X5};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000305};
CC Note=Binds 4 Zn(2+) ions per subunit. {ECO:0000305};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9SKC3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9SKC3-2; Sequence=VSP_036002;
CC -!- DOMAIN: Members of the RBR family are atypical E3 ligases. They
CC interact with the E2 conjugating enzyme UBE2L3 and function like HECT-
CC type E3 enzymes: they bind E2s via the first RING-type zinc finger, but
CC require an obligate trans-thiolation step during the ubiquitin
CC transfer, requiring a conserved active site Cys residue in the second
CC RING-type zinc finger. The active site probably forms a thioester
CC intermediate with ubiquitin taken from the active-site cysteine of the
CC E2 before ultimately transferring it to a Lys residue on the substrate.
CC {ECO:0000250|UniProtKB:Q9Y4X5}.
CC -!- SIMILARITY: Belongs to the RBR family. Ariadne subfamily.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABK28520.1; Type=Erroneous termination; Note=Extended C-terminus.; Evidence={ECO:0000305};
