Ações bioquímicas/fisiológicas

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.

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

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

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
