The authors have previously isolated a human gene from an endothelial cell cDNA library encoding a putative tyrosine kinase; they have designated this gene the fms-like gene (FLG). To analyze the gene products(s) of FLG, the authors have generated rabbit polyclonal antibodies directed against a synthetic peptide from FLG and used it to immunoprecipitate biosynthetically labeled FLG protein from a variety of human cell lines. These antibodies specifically recognized glycoprotein(s) of 100, 120, and 135 kDa with protein cores of 90 and 110 kDa. Acidic fibroblast growth factor (aFGF) stimulated tyrosine kinase activity of FLG in vitro and in living cells, suggesting that FLG encodes the membrane receptor for aFGF. Further supporting evidence came from cross-linking agent disuccinimidyl suberate and {sup 125}I-labeled aFGF as a specific probe. The cross-linked {sup 125}I-labeled aFGF-AFGF receptor complex was specifically immunoprecipitated with FLG antipeptide antibodies. It appears, therefore, that the receptor(s) for aFGF is related to the FLG gene product.
