Hepatocyte growth factor (HGF) is a pleiotropic cytokine responsible for regeneration, development and maintenance of various organs, and growth, invasion and metastasis of tumor cells. A full-length feline HGF cDNA was cloned and sequenced by RT-PCR from cat liver. Feline HGF consists of 728 amino acid and contains α- and β-chains encoded in a single open reading frame. The predicted amino acid sequence of feline HGF showed 93.2, 93.3 and 93.3% homology with those of human, mouse and rat HGF, respectively. The putative proteolytic processing site, all cysteine residues, and four potential glycosylation sites are conserved in all species. Therefore, feline HGF is expected to have a similar three-dimensional structure to human, mouse and rat HGF.
