TRAF family proteins. TRAF1 to TRAF6 share a conserved coiled-coil (CC)/TRAF-C domain, and TRAF7 has a series of 40 amino acid peptide repeats terminating in tryptophan (W) and aspartic acid (D) residues (WD40) domains. TRAFs, with the exception of TRAF1, have an N-terminal really interesting new gene (RING) domain and zinc finger motifs (Zn). Data are based on UniProt (https://www.uniprot.org).
