Mouse Apoptosis regulator BAX,BAX ELI

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.

BAX deficiency leads to lymphoid hyperplasia and male sterility, because of the cessation of sperm production.
