'''TNF receptor-associated factor''' (TRAF) are signal transducers and are involved in regulation of apoptosis, inflammation and antiviral response. 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<ref>PMID:11607847</ref>. '''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<ref>PMID:22017431</ref>. '''TRAF4''' is a binding partner of glycoproteins in platelets<ref>PMID:20946164</ref>.
