DESCRIPTION

Also known as TNR6_HUMAN, FAS, APT1, FAS1, TNFRSF6. Receptor for TNFSF6/FASLG. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. The secreted isoforms 2 to 6 block apoptosis (in vitro). Binds DAXX. Interacts with HIPK3 (By similarity). Part of a complex containing HIPK3 and FADD (By similarity). Binds RIPK1 and FAIM2 (PubMed:7538908, PubMed:10535980). Interacts with BABAM2 and FEM1B (PubMed:10542291, PubMed:15465831). Interacts with FADD (PubMed:21109225, PubMed:19118384). Interacts directly (via DED domain) with NOL3 (via CARD domain); inhibits death-inducing signaling complex (DISC) assembly by inhibiting the increase in FAS-FADD binding induced by FAS activation (By similarity). Interacts with CALM (PubMed:24914971). In the absence of stimulation, interacts with BIRC2, DDX3X and GSK3B. The interaction with BIRC2 and DDX3X is further enhanced upon receptor stimulation and accompanied by DDX3X and BIRC2 cleavage (PubMed:18846110).
