- A suggested positive control is human spleen tissue lysate.
- PA5-20090 can be used with blocking peptide PEP-0208.
Target Information
The inhibitors of apoptosis (IAP) proteins prevent cell death both in vitro and in vivo by inhibiting distinct caspases.
The X-linked Inhibitor of Apoptosis (XIAP) is a key member of this family.
XIAP’s caspase-inhibiting activity is negatively regulated by XIAP-associated factor 1 (XAF1) and Smac/DIABLO.
XAF1 binds to XIAP and antagonizes its inhibitory activity on caspases, leading to redistribution of XIAP from the cytosol to the nucleus.
XAF1 is ubiquitously expressed in normal tissues but is often reduced or absent in various cancer cell lines.
