Synonyms:CRADD, RAIDD Background:RAIDD, also named as CRADD, is an apoptotic adaptor molecule specific for caspase-2 and FASL/TNF receptor-interacting protein RIP. In the presence of RIP and TRADD, CRADD recruits caspase-2 to the TNFR-1 signalling complex. CRADD interacts with BCL10 through its caspase recruitment domain and suppresses interactions between BCL10 and CARMA1. It is a negative regulator of the CARMA1 signalosome and suppressor of Th1-and Th17-mediated inflammatory responses.
