Bovine 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 (By similarity).

Interacts (via a C-terminal 33 residues) with NOL3 (via CARD domain); inhibits BAX activation and translocation and consequently cytochrome c release from mitochondria (By similarity).
