Function
FADD_MOUSE Apoptotic adaptor molecule that recruits caspase-8 or caspase-10 to the activated Fas (CD95) or TNFR-1 receptors. The resulting aggregate called the death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation. Active caspase-8 initiates the subsequent cascade of caspases mediating apoptosis (By similarity). Involved in interferon-mediated antiviral immune response, playing a role in the positive regulation of interferon signaling (By similarity).

Publication Abstract from PubMed
A signal of Fas-mediated apoptosis is transferred through an adaptor protein Fas-associated death domain protein (FADD) by interactions between the death domains of Fas and FADD. To understand the signal transduction mechanism of Fas-mediated apoptosis, we solved the solution structure of a murine FADD death domain. It consists of six helices arranged in a similar fold to the other death domains. The interactions between the death domains of Fas and FADD analyzed by site-directed mutagenesis indicate that charged residues in helices alpha2 and alpha3 are involved in death domain interactions, and the interacting helices appear to interact in anti-parallel pattern, alpha2 of FADD with alpha3 of Fas and vice versa.
