General annotation (Comments)

Function	Promotes 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.
Subunit structure	Forms 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.
Subcellular location	Mitochondrion outer membrane. Cytoplasm. Note: Upon phosphorylation, locates to the cytoplasm.
Tissue specificity	Expressed in a wide variety of tissues.
Domain	Intact 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.
Post-translational modification	Phosphorylated 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 By similarity.
Sequence similarities	Belongs to the Bcl-2 family.
Sequence caution	The sequence AAB36516.1 differs from that shown. Reason: Frameshift at positions 64 and 91.
