FADD antibodies

FAS-associated death domain protein (FADD) is a 23 kDa adaptor protein involved in initiating apoptosis. FADD is best known for its involvement in extrinsic/death receptor-mediated apoptosis, but it is also involved in initiating necroptosis with serine/threonine kinases RIPK1 and RIPK3 (1). FADD binds to receptors of the tumor necrosis factor (TNF) superfamily through its C-terminal death domain (DD). During extrinsic apoptosis, binding of the Fas-ligand causes trimerization of the Fas-receptor which then binds to FADD via the DD domain.
