Tumor necrosis factor receptor 2

Tumor necrosis factor receptor 2 (TNFR2), also known as tumor necrosis factor receptor superfamily member 1B (TNFRSF1B) and CD120b, is one of two membrane receptors that binds tumor necrosis factor-alpha (TNFα).[5][6] Like its counterpart, tumor necrosis factor receptor 1 (TNFR1), the extracellular region of TNFR2 consists of four cysteine-rich domains which allow for binding to TNFα.[7][8] TNFR1 and TNFR2 possess different functions when bound to TNFα due to differences in their intracellular structures, such as TNFR2 lacking a death domain (DD).[7]

Function

edit

The protein encoded by this gene is a member of the tumor necrosis factor receptor superfamily, which also contains TNFRSF1A. This protein and TNF-receptor 1 form a heterocomplex that mediates the recruitment of two anti-apoptotic proteins, c-IAP1 and c-IAP2, which possess E3 ubiquitin ligase activity. The function of IAPs in TNF-receptor signalling is unknown, however, c-IAP1 is thought to potentiate TNF-induced apoptosis by the ubiquitination and degradation of TNF-receptor-associated factor 2 (TRAF2), which mediates anti-apoptotic signals. Knockout studies in mice also suggest a role of this protein in protecting neurons from apoptosis by stimulating antioxidative pathways.[9]

Clinical significance

edit

CNS

edit

At least partly because TNFR2 has no intracellular death domain, TNFR2 is neuroprotective.[10]

Patients with schizophrenia have increased levels of soluble tumor necrosis factor receptor 2 (sTNFR2).[11]

Cancer

edit

Targeting of TNRF2 in tumor cells is associated with increased tumor cell death and decreased progression of tumor cell growth.[8]

Increased expression of TNFR2 is found in breast cancer, cervical cancer, colon cancer, and renal cancer.[8] A link between the expression of TNRF2 in tumor cells and late-stage cancer has been discovered.[8] TNFR2 plays a significant role in tumor cell growth as it has been found that the loss of TNFR2 expression is linked with increased death of associated tumor cells and a significant standstill of further growth.[8] There is therapeutic potential in the targeting of TNFR2 for cancer treatments through TNFR2 inhibition.[12]

Systemic Lupus Erythematous (SLE)

edit

A small scale study of 289 Japanese patients suggested a minor increased predisposition from an amino acid substitution of the 196 allele at exon 6. Genomic testing of 81 SLE patients and 207 healthy patients in a Japanese study showed 37% of SLE patients had a polymorphism on position 196 of exon 6 compared to 18.8% of healthy patients. The TNFR2 196R allele polymorphism suggests that even one 196R allele results in increased risk for SLE.[13]
