CC -!- FUNCTION: Accelerates programmed cell death by binding to, and
CC antagonizing the apoptosis repressor BCL2 or its adenovirus homolog E1B
CC 19k protein. Under stress conditions, undergoes a conformation change
CC that causes translocation to the mitochondrion membrane, leading to the
CC release of cytochrome c that then triggers apoptosis. Promotes
CC activation of CASP3, and thereby apoptosis.
CC {ECO:0000250|UniProtKB:Q07812}.
CC -!- SUBUNIT: Homodimer. Forms higher oligomers under stress conditions.
CC Forms heterooligomers with BAK. Interacts with BCL2L11. Interaction
CC with BCL2L11 promotes BAX oligomerization and association with
CC mitochondrial membranes, with subsequent release of cytochrome c. Forms
CC heterodimers with BCL2, E1B 19K protein, BCL2L1 isoform Bcl-X(L),
CC BCL2L2, MCL1 and A1. Interacts with SH3GLB1. Interacts with SFN and
CC YWHAZ; the interaction occurs in the cytoplasm. Under stress
CC conditions, JNK-mediated phosphorylation of SFN and YWHAZ, releases BAX
CC to mitochondria. Interacts with RNF144B, which regulates the ubiquitin-
CC dependent stability of BAX. Interacts with CLU under stress conditions
CC that cause a conformation change leading to BAX oligomerization and
CC association with mitochondria. Does not interact with CLU in unstressed
CC cells (By similarity). Interacts with FAIM2/LFG2 (By similarity).
CC Interacts with BOP (By similarity). Interacts (via a C-terminal 33
CC residues) with NOL3 (via CARD domain); inhibits BAX activation and
CC translocationand consequently cytochrome c release from mitochondria
CC (PubMed:15383280). Interacts with GIMAP3/IAN4 and GIMAP5/IAN5; this
CC interaction is increased, when cells initiate apoptosis upon IL2
CC withdrawal (By similarity). Interacts with IRF3; the interaction is
CC direct and, upon virus infection, mediates the formation of the
CC apoptosis complex TOMM70:HSP90AA1:IRF3:BAX (By similarity). Interacts
CC with MOAP1, facilitating BAX-dependent mitochondrial outer membrane
CC permeabilization and apoptosis (By similarity). Interacts with
CC BCL2L10/BCL-B (By similarity). {ECO:0000250|UniProtKB:Q07812,

CC Note=Colocalizes with 14-3-3 proteins in the cytoplasm. Under stress
CC conditions, undergoes a conformation change that causes release from
CC JNK-phosphorylated 14-3-3 proteins and translocation to the
CC mitochondrion membrane (By similarity). {ECO:0000250|UniProtKB:Q07812}.

CC highest levels in the testis and ovary.
CC -!- DOMAIN: Intact BH3 motif is required by BIK, BID, BAK, BAD and BAX for
