摘要:
The present invention relates to an action between an inhibitor of apoptosis (IAP) protein and members of the caspase family of cell death proteases, for example, an interaction of the X chromosome linked IAP (XIAP) and caspase-3, caspase-7 or caspase-9, wherein the IAP regulates the activity of the caspases. The invention provides screening assays for identifying agents that alter the specific association of an IAP such as XIAP, c-IAP-1 or c-IAP-2 and a caspase such as caspase-3 or caspase-7 or a pro-caspase such as pro-caspase-9, or that modulate the activity of a caspase in the presence of an IAP and that regulate the activation of a pro-caspase by an IAP. The invention further provides methods of reducing the severity of a pathologic condition in an individual by administering to the individual an agent that alters the caspase inhibitory activity of an IAP.
