CC -!- FUNCTION: E3 ubiquitin-protein ligase which accepts ubiquitin from E2
CC ubiquitin-conjugating enzymes UBE2L3 and UBE2L6 in the form of a
CC thioester and then directly transfers the ubiquitin to targeted
CC substrates such as LCMT2, thereby promoting their degradation. Induces
CC apoptosis via a p53/TP53-dependent but caspase-independent mechanism.
CC However, its overexpression also produces a decrease of the ubiquitin-
CC dependent stability of BAX, a pro-apoptotic protein, ultimately leading
CC to protection of cell death; But, it is not an anti-apoptotic protein
CC per se (By similarity). {ECO:0000250}.
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:O60260};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Interacts with UBE2L3, UBE2L6 and LCMT2 as well as with BAX.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane; Single-pass membrane
CC protein. Cytoplasm. Note=Mostly cytosololic, accumulates in
CC submitochondrial domains specifically upon apoptosis induction, in
CC synchrony with BAX activation. {ECO:0000250}.
CC -!- DOMAIN: The RING-type zinc finger domain mediates binding to an E2
CC ubiquitin-conjugating enzyme. The transmembrane domain is essential for
CC translocation to the mitochondria upon induction of apoptosis (By
CC similarity). {ECO:0000250}.
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 -!- PTM: Auto-ubiquitinated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the RBR family. RNF144 subfamily. {ECO:0000305}.
CC -!- CAUTION: Lacks the His residue in the RING-type domain 2 that is one of
CC the conserved features of the family. {ECO:0000305}.
