Description
Tumor Necrosis Factor Receptor Superfamily Member 1B (TNFRSF1B) is a member of the Tumor Necrosis Factor Receptor Superfamily. TNFRSF1B contains four TNFR-Cys repeats. TNFRSF1B can be cleaved into the following 2 chains: Tumor necrosis factor receptor superfamily member 1b and membrane form and Tumor necrosis factor-binding protein 2. TNFRSF1B is a receptor with high affinity for TNFSF2/TNF- alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin- alpha. TNFRSF1B mediates most of the metabolic effects of TNF- alpha. TNF- alpha-induced apoptosis suggests that it regulates TNF- alpha function by antagonizing its biological activity
