ARTS (Sept4_i2) is a pro-apoptotic tumor suppressor protein that functions as an antagonist of X-linked IAP (XIAP) to promote apoptosis. ARTS-induced caspase activation leads to cleavage of the pro-apoptotic Bcl-2 family protein Bid known to Opicapone (BIA 9-1067) promote MOMP. We propose that translocation of ARTS initiates a first wave of caspase activation that can… Continue reading ARTS (Sept4_i2) is a pro-apoptotic tumor suppressor protein that functions as
