Protein Information
Description
Protein function:
Receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. 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. Contributes to the induction of noncytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase.
Subunit:
Binding of TNF to the extracellular domain leads to homotrimerization. The aggregated death domains provide a novel molecular interface that interacts specifically with the death domain of tradd. Various tradd-interacting proteins such as trafs, rip and possibly fadd, are recruited to the complex by their association with tradd. This complex activates at least two distinct signaling cascades, apoptosis and NF-kappa-b signaling. Binds bag4. Constitutively associated with trpc4ap. Interacts with hcv core protein.
Subcellular location:
Type I membrane protein and secreted.
Post-translational modification:
The soluble form is produced from the membrane form by proteolytic processing.
Similarity:
Contains 1 death domain.
