COP Proteins and Enzymes

Caspase inhibitor. Acts as a regulator of procaspase-1/CASP1 activation implicated in the regulation of theproteolytic maturation of pro-interleukin-1 beta (IL1B) and its release during inflammation. Inhibits the release ofIL1B in response to LPS in monocytes. Also induces NF-kappa-B activation during the pro-inflammatory cytokineresponse. Also able to inhibit CASP1-mediated neuronal cell death, TNF-alpha, hypoxia-, UV-, andstaurosporine-mediated cell death but not ER stress-mediated cell death. Acts by preventing activation of caspasesCASP1 and CASP4, possibly by preventing the interaction between CASP1 and RIPK2
