Background

Function
BAX (BCL2-associated X protein) is a pro-apoptotic member of the BCL-2 family that regulates programmed cell death through mitochondrial apoptosis and functions as a critical determinant of cellular survival following apoptotic stimuli[1][2]. BAX forms heterodimers with anti-apoptotic BCL-2 proteins, and the balance between BAX and BCL-2 influences mitochondrial outer membrane permeabilization (MOMP), cytochrome c release, and activation of the intrinsic apoptotic pathway[2][3][4]. Mechanistically, BAX belongs to the pore-forming executioner subgroup of the BCL-2 family and undergoes activation in response to cellular stress signals, including p53-dependent apoptotic signaling, thereby promoting mitochondrial membrane permeabilization and irreversible cell death commitment[1][3][5]. In disease models, dysregulated BAX activity contributes to the pathophysiology of cancer, neurodegenerative disorders, and other apoptosis-associated conditions, making mitochondrial apoptosis a major target for therapeutic intervention[3][4][6]. Compared with related BCL-2 family isoforms, BAX is distinguished by its direct executioner function in apoptosis, whereas many alternative BCL-2 family isoforms display variable anti-apoptotic or context-dependent activities that remain incompletely characterized[3]. A notable BAX isoform, BaxΔ2, retains pro-apoptotic activity despite N-terminal alterations, highlighting functional diversity within the BAX locus and providing experimental models for studying non-canonical apoptotic mechanisms[7]. For experimental applications, BAX-dependent signaling is widely used to evaluate mitochondrial apoptosis, while therapeutic strategies targeting BCL-2 family interactions, including BH3 mimetics, are actively investigated to modulate BAX-mediated cell death in cancer research[3][6].

Expression
Tissue_specificity:This gene is expressed in a variety of tissues. The Psi isoform is present in gliomas. The α isoform is expressed in the spleen, breast, ovary, testis, colon, and brain, and at low levels in the skin and lungs. The Sigma isoform is expressed in the spleen, breast, ovary, testis, lung, colon, and brain, and at low levels in the skin. Both the α and Sigma isoforms are expressed in promyelocytic leukemia, histiocytic lymphoma, Burkitt lymphoma, T-cell lymphoma, lymphoblastic leukemia, breast adenocarcinoma, ovarian adenocarcinoma, prostate cancer, prostate adenocarcinoma, lung cancer, epidermoid carcinoma, small cell lung cancer, and colon adenocarcinoma cell lines. -
Subunit
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, PubMed: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, PubMed:16199525). Interacts with BCL2L10/BCL-B (PubMed:23235460). Interacts with non-acetylated XRCC6/Ku70; this interaction leads to BAX sequestration in the cytosol, away from the mitochondria, preventing BAX-mediated apoptosis (PubMed:15023334)
