    Abstract

    Fibroblast growth factor 4 (FGF4) is considered a crucial gene in the development of mammalian embryos. Here we identified common amino acid sequences predicted from coding exons of the FGF4 gene in five pigs of two breeds, and HispFGF4, a 6× histidinetagged porcine FGF4, was produced in Escherichia coli. HispFGF4 was purified efficiently from the supernatant of cell lysate by heparin column chromatography. In a porcine embryonic fibroblast cell line, HispFGF4 showed significant mitogenic activities at concentrations as low as 0.001 nM (p < 0:01). To the best of our knowledge, this is the first report describing the complete nucleotide sequence of coding exons for the porcine FGF4 protein in two breeds, together with the production of a recombinant, bioactive porcine FGF4 derivative.
