- p75 TNF receptor
FunctionReceptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity.
Sequence similaritiesContains 4 TNFR-Cys repeats.
modificationsPhosphorylated; mainly on serine residues and with a very low level on threonine residues.
A soluble form (tumor necrosis factor binding protein 2) is produced from the membrane form by proteolytic processing.
Cellular localizationSecreted and Cell membrane.
