Actions biochimiques/physiologiques

When cells receive apoptotic stimuli, such as activation of the TNFα/Fas cell surface receptor, caspase 8 activation, Bid processing and its translocation to the mitochondria ensue. As a result mitochondria release cytochrome c which then binds to Apaf-1, the mammalian Ced-4 homologue, together with dATP. The resultant complex recruits caspase 9 leading to its activation. It then cleaves downstream caspases such as caspase 3, 6, and 7, initiating the caspase cascade. Caspase 9 exhibits basal activity. It can be further activated via interaction of its N-terminal prodomain with the activator protein Apaf-1 in the presence of cytochrome c and dATP. Caspases have been implicated in many disorders including cancer, inflammatory disease, neurodegenerative diseases, stroke and myocardial infarction.

The recombinant form of the proapoptotic caspase-9 purified following expression in Escherichia coli is processed at Asp315, but largely inactive; however, when added to cytosolic extracts of human 293 cells it is activated 2000-fold in the presence of cytochrome c

Members of the ICE/Ced-3 gene family are likely effector components of the cell death machinery. Here, we characterize a novel member of this family designated ICE-LAP6. By phylogenetic analysis, ICE-LAP6 is classified into the Ced-3 subfamily which includes Ced-3, Yama/CPP32/apopain

Caspase-9 is a member of caspase family of cysteine proteases that have been implicated in apoptosis and cytokine processing. When cells receive apoptotic stimuli, mitochondria releases cytochrome c which then binds to Apaf-1, the mammalian Ced-4 homologue, together with dATP.

Recent evidence suggests that CPP32 is an essential component of an aspartate-specific cysteine protease (ASCP) cascade responsible for apoptosis execution in mammalian cells. Activation of CPP32 could lead to activation of other downstream ASCPs, resulting in late morphological changes such
