摘要
Mitochondria-mediated apoptosis plays a central role in animal development and tissue homeostasis, and its alteration results in a range of malignant disorders including cancer. Upon apoptotic stimuli, the mitochondrial proteins cytochrome c and Smac/DIABLO are released into the cytosol. where they synergistically activate caspases by activating Apaf-1 and relieving the apoptotic inhibition by IAPs. Recent biochemical and structural studies reveal a molecular basis for these important events and identify an evolutionarily conserved mechanism of apoptosis from fruit flies to mammals.
