Homodimer. Forms higher oligomers under stress conditions. Forms heterooligomers with BAK (PubMed:29531808). Interacts with BCL2L11. Interaction with BCL2L11 promotes BAX oligomerization and association with mitochondrial membranes, with subsequent release of cytochrome c. Forms heterodimers with BCL2, BCL2L1 isoform Bcl-X(L), BCL2L2, MCL1 and A1 (PubMed:25609812). Interacts with SH3GLB1. Interacts with humanin; forms fibers with humanin which results in BAX conformational changes and sequestering of BAX into the fibers, preventing BAX activation (PubMed:12732850, 31690630). Interacts with SFN and YWHAZ; the interaction occurs in the cytoplasm. Under stress conditions, JNK-mediated phosphorylation of SFN and YWHAZ, releases BAX to mitochondria. Interacts with RNF144B, which regulates the ubiquitin-dependent stability of BAX. Interacts with CLU under stress conditions that cause a conformation change leading to BAX oligomerization and association with mitochondria. Does not interact with CLU in unstressed cells. Interacts with FAIM2/LFG2. Interacts with RTL10/BOP. Interacts (via a C-terminal 33 residues) with NOL3 (via CARD domain); inhibits BAX activation and translocation and consequently cytochrome c release from mitochondria. Interacts with GIMAP3/IAN4 and GIMAP5/IAN5; this interaction is increased, when cells initiate apoptosis upon IL2 withdrawal (PubMed:16509771). Interacts with IRF3; the interaction is direct, increases upon Sendai virus infection and mediates the formation of the apoptosis complex TOMM70:HSP90AA1:IRF3:BAX (PubMed:25609812). Interacts with MOAP1, facilitating BAX-dependent mitochondrial outer membrane permeabilization and apoptosis (PubMed:11060313, 16199525). Interacts with BCL2L10/BCL-B (PubMed:23235460). [Isoform Sigma]: Interacts with BCL2A1 and BCL2L1 isoform Bcl-X(L). (Microbial infection) Interacts with adenovirus E1B 19K protein; this interaction blocks BAX oligomerization (PubMed:11462023). (Microbial infection) Interacts with human cytomegalovirus/HHV-5 protein vMIA/UL37. (Microbial infection) Interacts with enterovirus protein 2B; this interaction activates BAX-induced apoptosis.
