General description

FADD or Fas-Associated protein with Death Domain is an adaptor molecule that mediates death signaling by the Fas-receptor, tumor necrosis factor receptor and TRAIL-receptor. FADD binds to these receptors via the C-terminus Death Domain which then unmasks the N-terminal effector domain of FADD thereby allowing it to recruit caspase-8 and activate the cysteine protease cascade leading to apoptosis. Cells lacking FADD are defective in intracellular double-stranded RNA (dsRNA)-activated gene expression, including production of type I (alpha/beta) interferons and are thus very susceptible to viral infection.
