Abstract

Abstract The present invention relates to the production of large quantities of a novel chimeric TGF-β, termed TGF-β1/β2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-β1/β2 precursor coding sequence controlled by expression regulatory elements. Simian TGF-β1 cDNA (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-β1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-β2 structure. Simian codon usage was maintained. The chimeric TGF-β1/β2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-β1.
