The human FGF6 gene is an oncogene related by sequence similarities to the fibroblast growth factor (FGF) gene family, which encodes mitogenic peptides implicated in various physiological processes including angiogenesis, morphogenesis, tissue regeneration and survival and oncogenesis. Nucleotide sequence analysis of the FGF6 gene and of cDNA clones revealed an open reading frame able to code for a protein of 208 residues. The FGF6 protein shares 32-70% residues with the other members of the family within the C-terminal two-thirds of the molecule. In vitro, three in-frame ATG codons are able to initiate the translation of three peptides of 175, 198 and 208 residues. These three peptides differ at their amino termini with respect to the relative position of a hydrophobic leader peptide, which extends from residues 16 to 40, and is therefore absent from the shorter (175 amino acids) form. In-vitro analysis indicates that this signal peptide is able to drive the FGF6 protein through the endoplasmic reticulum, where it becomes glycosylated. The presence of this signal peptide sequence appears essential for the in vivo transforming capacity of the FGF6 gene.
