Prosurvival AMBRA1 turns into a proapoptotic BH3-like protein during mitochondrial apoptosis

Abstract excerpt

Autophagy and apoptosis are 2 stress-response mechanisms that are closely interconnected. However, the molecular interplays between these 2 pathways remain to be clarified. Here we report that the crucial proautophagic factor AMBRA1 can act as a positive mediator of mitochondrial apoptosis. Indeed, we show that, in a proapoptotic positive feedback loop, the C-terminal part of AMBRA1, generated by CASP/CASPASE...
