?cl12111: TNFR Superfamily (this model, PSSM-Id:276021 is obsolete)
Tumor necrosis factor receptor (TNFR) domain; superfamily of TNF-like receptor domains. When bound to TNF-like cytokines, TNFRs trigger multiple signal transduction pathways, they are involved in inflammation response, apoptosis, autoimmunity and organogenesis. TNFRs domains are elongated with generally three tandem repeats of cysteine-rich domains (CRDs). They fit in the grooves between protomers within the ligand trimer. Some TNFRs, such as NGFR and HveA, bind ligands with no structural similarity to TNF and do not bind ligand trimers.
