Two genes, flg and bek, have been recently shown to encode receptors for fibroblast growth factors (FGF). Here we report the molecular cloning and sequence of a new member of the FGF receptor family, denoted flg-2, which was isolated from a human keratinocyte cDNA library. The cDNA sequence predicts an extracellular region possessing three immunoglobulin-like domains, a single transmembrane region and a cytoplasmic portion containing the tyrosine kinase domain split by a short inter-kinase segment. The amino acid sequence of flg-2 shows 68% and 64% identity with bek and flg, respectively. The most variable domain among the three genes is the amino-terminal immunoglobulin-like domain. Comparison with the chicken FGF receptor genes suggests that flg-2 is homologous to cek-2, whereas flg and bek are homologous to cek-1 and cek-3, respectively. Analysis of mRNA from various tissues shows that flg-2 is expressed predominantly in skin, brain and lung.

D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
