NCIt definition : Human XAF1 is located in the vicinity of 17p13.2 and is approximately 20 kb in length.
This gene, which encodes XIAP-associated factor 1 protein, is involved in apoptosis
and caspase inhibition.;
NCIt note : HSXIAPAF1 antagonizes the anticaspase activity of XIAP and may be important in mediating
apoptosis resistance in cancer cells. This is associated with the nuclear redistribution
of XIAP, as cytoplasmic XAF1 appears to antagonize nuclear XIAP inhibition of CASP3
activity.;
