1F2H - PubMed Abstract:
TRADD is a multifunctional signaling adaptor protein that is recruited to TNFR1 upon ligand binding. The C-terminal of TRADD comprises the "death domain" that is responsible for association of TNFR1 and other death domain-containing proteins such as FADD and RIP. The N-terminal domain (N-TRADD) promotes the recruitment of TRAF2 to TNFR1 by binding to the C-terminal of TRAF2, leading to the activation of JNK/AP1 and NF-kappa B. The solution structure of N-TRADD was determined, revealing a novel protein fold. A combination of NMR, BIAcore, and mutagenesis experiments was used to help identify the site of interaction of N-TRADD with C-TRAF2, providing a framework for future attempts to selectively inhibit the TNF signaling pathways.
