Name :
Human TNFR2 Protein, ECD (Extracellular Domain), Fc-fusion, Biotinylated, Recombinant
Description :
TNFR1 and TNFR2 are single-pass, type I transmembrane glycoproteins that are two distinct types of highaffinity cell surface receptors for TNF. Both receptors are the founding members of the TNF receptor superfamily (TNFRSF) and are designated TNFRSF1A and TNFRSF1B, respectively. The extracellular regions of both receptors contain 4 conserved cysteinerich repeats that mediate the interaction with TNF. However their intracellular sequences have no homology, indicative of distinct signaling pathways. TNFR1 and TNFR2 form a heterocomplex on the cell surface that mediates the recruitment of adaptor proteins for signal transduction. Soluble truncated forms of TNFR1 and TNFR2 have been identified in human serum and urine, which can neutralize the biological activities of TNF. Whereas all cell types studied express TNFR1, TNFR2 expression is limited primarily to hematopoietic cells and cells of the immune system. TNFR2 mediates most of the metabolic effects of TNF. TNFR2 binds with high affinity to TNF-α and approximately 5-fold lower affinity to TNF-β. The soluble form of TNFR2 is produced from the membrane form by proteolytic processing and is clinically used to treat moderate to severe rheumatoid arthritis (RA). In addition high plasma levels of soluble TNFR2 are associated with increased incidence of coronary heart disease.

Construct Details :
The recombinant human TNFR2-Fc fusion is expressed as a 460 amino acid protein consisting of Leu23 – Asp257 region of TNFR2 (UniProt accession #P20333) and a C-terminal Fc from human IgG1, which exists as a dimer/tetramer under non-reducing conditions (see the gel image above).
