Apoptosis is related to many diseases and development.
Caspase-9 plays a central role in cell death induced by a variety of apoptosis activators.
Cytochrome c, after released from mitochondria, binds to Apaf-1, which forms an apoptosome that in turn binds to and activate procaspase-9.
Activated caspase-9 cleaves and activates the effector caspases (caspase-3,-6 and –7), which are responsible for the proteolytic cleavage of many key proteins in apoptosis.
The tumor suppressor putative HLA-DR-associated proteins ( PHAPs ) were recently identified as important regulators of mitochondrion apoptosis (1).
PHAP appears to facilitate apoptosome-medicated caspase-9 activation and to stimulate the mitochondrial apoptotic pathway.
PHAP was also shown to oppose both Ras and Myc-mediated cell transformation.
Applications:Suitable for use in ELISA, Western Blotting.
