an adaptor molecule that mediates apoptosis. Recruited through its C-terminal death domain by Fas-receptor, tumor necrosis factor receptor, TNFRSF25, and TRAIL-receptor, participating in the death signaling initiated by these receptors. Interaction with the receptors unmasks the N-terminal effector domain of this protein, which recruits caspase-8, and thereby activates the cysteine protease cascade. Knockout studies in mice also suggest the importance of this protein in early T cell development. Note: This description may include information from UniProtKB.
