TRADD Protein, Human (His)

The TRADD protein acts as a linker for TNFRSF1A/TNFR1 and mediates its interaction with FADD. TRADD induces TNF-induced responses: apoptosis and NF-kappa-B activation. TRADD Protein, Human (His) is the recombinant human-derived TRADD protein, expressed by E. coli , with C-6*His labeled tag.

The TRADD protein serves as an adapter molecule for TNFRSF1A/TNFR1, specifically associating with the cytoplasmic domain of activated TNFRSF1A/TNFR1 to mediate its interaction with FADD. Overexpression of TRADD induces two major TNF-induced responses: apoptosis and activation of NF-kappa-B. The nuclear form of TRADD acts as a tumor suppressor by preventing the ubiquitination and degradation of isoform p19ARF/ARF of CDKN2A through interaction with TRIP12, disrupting the interaction between TRIP12 and isoform p19ARF/ARF of CDKN2A. Stimulation of TNF-alpha receptor TNFRSF1A leads to the formation of two distinct signaling complexes. Plasma membrane-bound complex I, composed of TNFRSF1A, TRADD, RIPK1, TRAF2, and BIRC2/c-IAP1 or BIRC3, interacts with CHUCK/IKK-alpha, IKBKB/IKK-beta, and IKBKG/IKK-gamma, promoting cell survival. Subsequently, TRADD, RIPK1, and TRAF2 dissociate from TNFRSF1A to form cytoplasmic complex II with FADD and caspase CASP8, promoting cell apoptosis. TRADD also interacts with various proteins within these complexes, including TRPC4AP, UXT1, DAB2IP, SQSTM1, TRIP12, HIPK2, KRT14, KRT18, KRT16, KRT17, FADD, and TOMM70, highlighting its multifaceted role in diverse cellular processes.
