FunctionRequired for death receptor-dependent apoptosis. When associated with RASSF1, promotes BAX conformational change and translocation to mitochondrial membranes in response to TNF and TNFSF10 stimulation.
Tissue specificityUbiquitously expressed with higher levels in heart and brain.
Sequence similaritiesBelongs to the PNMA family.
DomainThe BH3-like domain is required for association with BAX and for mediating apoptosis. The three BH domains (BH1, BH2, and BH3) of BAX are all required for mediating protein-protein interaction.
