Comment typeDescription
CautionThe protein name 'Bcl2 antagonist of cell death' may be misleading. The protein antagonises Bcl2-mediated repression of cell death, hence it promotes apoptosis. {ECO:0000305}.
DomainIntact BH3 motif is required by BIK, BID, BAK, BAD and BAX for their pro-apoptotic activity and for their interaction with anti-apoptotic members of the Bcl-2 family.
FunctionPromotes cell death. Successfully competes for the binding to Bcl-X(L), Bcl-2 and Bcl-W, thereby affecting the level of heterodimerization of these proteins with BAX. Can reverse the death repressor activity of Bcl-X(L), but not that of Bcl-2 (By similarity). Appears to act as a link between growth factor receptor signaling and the apoptotic pathways. {ECO:0000250}.

PtmMethylation at Arg-94 and Arg-96 by PRMT1 inhibits Akt- mediated phosphorylation at Ser-99. {ECO:0000269|PubMed:10926925, ECO:0000269|PubMed:21444773}.
PtmPhosphorylated on one or more of Ser-75, Ser-99, Ser-118 and Ser-134 in response to survival stimuli, which blocks its pro- apoptotic activity. Phosphorylation on Ser-99 or Ser-75 promotes heterodimerization with 14-3-3 proteins. This interaction then facilitates the phosphorylation at Ser-118, a site within the BH3 motif, leading to the release of Bcl-X(L) and the promotion of cell survival. Ser-99 is the major site of AKT/PKB phosphorylation, Ser-118 the major site of protein kinase A (CAPK) phosphorylation. Phosphorylation at Ser-99 by PKB/AKT1 is almost completely blocked by the apoptotic C-terminus cleavage product of PKN2 generated by caspases-3 activity during apoptosis. {ECO:0000269|PubMed:10926925, ECO:0000269|PubMed:11278822, ECO:0000269|PubMed:12897128, ECO:0000269|PubMed:16818649, ECO:0000269|PubMed:18669648, ECO:0000269|PubMed:19690332}.
Sequence CautionSequence=AAB36516.1; Type=Frameshift; Positions=64, 91; Evidence={ECO:0000305};
SimilarityBelongs to the Bcl-2 family. {ECO:0000305}.
Subcellular LocationMitochondrion outer membrane. Cytoplasm. Note=Upon phosphorylation, locates to the cytoplasm.
SubunitForms heterodimers with the anti-apoptotic proteins, Bcl- X(L), Bcl-2 and Bcl-W. Also binds protein S100A10 (By similarity). The Ser-75/Ser-99 phosphorylated form binds 14-3-3 proteins (By similarity). Interacts with AKT1 and PIM3. {ECO:0000250, ECO:0000269|PubMed:10926925, ECO:0000269|PubMed:17270021}.
Tissue SpecificityExpressed in a wide variety of tissues.
