Inhibits TNFRSF1A, TNFRSF6, TNFRSF10 and TNFRSF12 induced apoptosis. May interfere with caspase-8 recruitment and activation at the death-inducing signaling complex (DISC). May lead to higher virus production and contribute to virus persistence and oncogenicity. Associates with the death-inducing signaling complex (DISC) formed by TNFRSF6, FADD and caspase-8. Interacts with FADD.
