General description
BCL2 associated X, apoptosis regulator (BAX) is a proapoptotic protein of the B-cell lymphoma 2 (BCL2) protein family. The gene encoding it is localized on human chromosome 19q13.33.
Biochem/physiol Actions
BCL2 associated X, apoptosis regulator (BAX) forms a heterodimer with B-cell lymphoma 2 (BCL2) and functions as an apoptotic activator. BAX interacts with and increases the opening of the mitochondrial voltage-dependent anion channel (VDAC), which leads to the loss in the mitochondrial membrane potential and the release of cytochrome c. The expression of BAX gene is regulated by the tumor suppressor p53 and BAX has been shown to be involved in p53-mediated apoptosis. Multiple alternatively spliced transcript variants, which encode different isoforms, have been reported for this gene.
