The inhibitor of apoptosis protein (IAP) family consists of a number of evolutionarily conserved proteins that function to inhibit programmed cell death. X-linked IAP (XIAP) was cloned due to its sequence homology with other family members and has previously been shown to prevent apoptosis by binding to active caspases 3, 7, and 9 in vitro. XIAP transcripts(More)
In addition to its well described function as an enzymatic inhibitor of specific caspases, X-linked inhibitor of apoptosis (X-linked IAP or XIAP) can function as a cofactor in Smad, NF-kappaB, and JNK signaling pathways. However, caspases themselves have been shown to regulate the activity of a number of signaling cascades, raising the possibility that the(More)
Inhibitor of apoptosis protein (IAP)-like protein-1 (ILP-1) (also known as X-linked IAP [XIAP] and mammalian IAP homolog A [MIHA]) is a potent inhibitor of apoptosis and exerts its effects, at least in part, by the direct association with and inhibition of specific caspases. Here, we describe the molecular cloning and characterization of a human gene(More)
