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;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16823372}. Nucleus
CC {ECO:0000269|PubMed:16823372}.
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 domain, but require
CC an obligate trans-thiolation step during the ubiquitin transfer,
CC requiring a conserved cysteine residue in the second RING domain.
CC {ECO:0000250|UniProtKB:O60260}.
CC -!- SIMILARITY: Belongs to the RBR family. {ECO:0000305}.
