Apoptosis regulator BAX is a protein in humans that is encoded by BAX gene. Accelerates programmed cell death by binding to, and antagonizing the apoptosis repressor BCL2 or its adenovirus homolog E1B 19k protein. Under stress conditions, undergoes a conformation change that causes translocation to the mitochondrion membrane, leading to the release of cytochrome c that then triggers apoptosis. Promotes activation of CASP3, and thereby apoptosis.

As a member of the Bax subfamily that belongs to the Bcl-2 family of proteins, Bcl-2-associated X protein (BAX) is a pro-apoptotic protein encoded by the BAX gene [1]. BAX contains conserved Bcl-2 homology domains (BH1, BH2, BH3, and BH4)and a hydrophobic region at the C-terminal ends that are believed to serve as a membrane-spanning domain [1][2]. BAX expression is regulated by the tumor suppressor P53, and it is involved in P53-mediated apoptosis. Although the subcellular localization of Bax has not been known, Bax has been suggested to colocalize within the same subcellular compartments as Bcl-2 due to the presence of its putative C-terminal transmembrane segment and its ability to dimerize with Bcl-2 [3]. A majority of BAX proteins are found in the cytosol before apoptosis induction [4][5]. Upon the induction of apoptotic signals, BAX undergoes a conformation alteration, making itself translocate from the cytosol to mitochondria [4][5] where it participates in mitochondrial disruption and the release of cytochrome c. The loss of cytochrome c from mitochondria disables energy production, and cytosolic cytochrome c triggers a proteolytic cascade that dismantles the cell, namely apoptosis. Regulating the insertion of BAX into the mitochondrial outer membrane can regulate apoptosis [6][7]. Extensive mutagenesis studies have shown that the docking of BAX to mitochondria is dependent on its C-terminal sequence. The conformational change of the BAX C-terminus exposes the hydrophobic BH3 binding pocket that is involved in dimer formation, thus modulating the subcellular location of BAX and apoptosis [8]. Studies have proved that drugs such as ABT737 and a BH3 mimetic, that activate BAX, are the potential to be anticancer therapies by inducing apoptosis in cancer cells [9].
