Tumour necrosis factor receptor 7 (IPR022328)

Short name: TNFR_7

Family relationships

None.

Description

The tumour necrosis factor (TNF) receptor (TNFR) superfamily comprises more than 20 type-I transmembrane proteins. Family members are defined based on similarity in their extracellular domain -a region that contains many cysteine residues arranged in a specific repetitive pattern [PMID: 7917108]. The cysteines allow formation of an extended rod-like structure, responsible for ligand binding [PMID: 8387891].

Upon receptor activation, different intracellular signalling complexes are assembled for different members of the TNFR superfamily, depending on their intracellular domains and sequences [PMID: 15500863]. Activation of TNFRs can therefore induce a range of disparate effects, including cell proliferation, differentiation, survival, or apoptotic cell death, depending upon the receptor involved [PMID: 11239407, PMID: 9826575].

TNFRs are widely distributed and play important roles in many crucial biological processes, such as lymphoid and neuronal development, innate and adaptive immunity, and maintenance of cellular homeostasis [PMID: 15500863]. Drugs that manipulate their signalling have potential roles in the prevention and treatment of many diseases, such as viral infections, coronary heart disease, transplant rejection, and immune disease [PMID: 9826574].

TNF receptor 7, otherwise known as CD27 antigen, is expressed on discrete subpopulations of T-and B-cells [PMID: 9177220]. The receptor plays a vital role in the generation and long-term maintenance of T-cell immunity [PMID: 11062504].
