A novel fibroblast growth factor receptor-5 preferentially expressed in the pancreas(1).

Using the polymerase chain reaction on human embryonic cDNAs, we isolated a cDNA encoding a novel 504 amino acid protein, termed fibroblast growth factor receptor (FGFR)-5, which is highly homologous to known FGFRs. The NH(2)-terminal portion of FGFR5 contains a putative secretory signal sequence, three typical immunoglobulin-like domains, six cysteines, and an acidic box, but no HAV motif. The COOH-terminal portion of FGFR5 contains one transmembrane domain but no intracellular kinase domain. Recombinant FGFR5 expressed in COS-7 cells is not secreted, but recombinant truncated FGFR5 lacking the predicted transmembrane domain is secreted. Acidic fibroblast growth factor (aFGF) and basic fibroblast growth factor ( bFGF) do not bind to FGFR5. Among 23 adult human tissues, FGFR5 mRNA is preferentially expressed in the pancreas. These results suggest that FGFR5 may provide a binding site for some other fibroblast growth factors and may regulate some pancreatic function.[1]
