There are 7 known TRAF proteins. All TRAF proteins share a C-terminal homology region named TRAF domain which can bind the cytoplasmic domain of receptors and other TRAF proteins[1]. TRAF1 is the only TRAF which does not have N-terminal RING and zinc finger motifs. TRAF2, TRAF5 and TRAF6 mediate activation of NF-κB and JNK. TRAF3 mediates some innate immune receptor signals and regulates some post-translational modifications[2]. TRAF4 is a binding partner of glycoproteins in platelets[3]. Structural highlights The interaction of TRAF2 with the adaptor protein TRADD is [4]. Hydrophobic, Polar 3D Structures of TNF receptor-associated factor TNF receptor-associated factor 3D structures
