Activity

Measured by its binding ability in a functional ELISA.

200 ng/mL of biotinylated Recombinant Mouse FGF1 is mixed with serially diluted Recombinant Mouse FGF R5 Fc Chimera. Following incubation, the FGF R5-FGF1/biotin complex is captured on an EvenCoatTM Streptavidin Microplate (Catalog # CP003). Bound FGF R5 is measured using Rt x mFGF R5 followed by HRP labeled Gt x Rat IgG. The concentration of Recombinant Mouse FGF R5 Fc Chimera that produces 50% of the optimal binding is 30-120 ng/mL.

Background: FGFR5/FGFRL1

Fibroblast growth factor receptor 5 (FGF R5), also known as FGRL1, is a 65 kDa transmembrane member of the FGF receptor family (1). Mature mouse FGF R5 consists of a 354 amino acid (aa) extracellular domain (ECD) with three immunoglobulin-like domains, a 21 aa transmembrane segment, and a 134 aa cytoplasmic domain (2). FGF R5 is distinct from other FGF receptor family members in that it does not contain a cytoplasmic tyrosine kinase domain (2, 3). Within the ECD, mouse FGF R5 shares 94% and 98% aa sequence identity with human and rat FGF R5, respectively. Alternate splicing results in an isoform that lacks the first Ig-like domain (2). FGF R5 is widely expressed, and expression of two species of mRNA in cartilage and pancreas may indicate the presence of both splice forms (2 - 6). Both the full length and truncated isoforms of FGF R5 bind FGF basic; the full length form additionally binds to heparin (2, 6). FGF R5 may function as a decoy receptor by binding FGF but not transducing its mitogenic signals (6).
