Cloning and nucleotide sequencing of sheep growth hormone cDNA

cDNA was prepared from the mRNA isolated from sheep anterior pituitary glands. On cloning cDNA in E. coli, a clone coding full sequence of sheep pre-growth hormone was determined. The sequence for the sheep growth hormone (GH) is in agreement with the amino acid sequence of the protein determined previously except for the asparagine residue at position 99 rather than aspartic acid and the arginine residue at position 146 in place of threonine. The cDNA sequence presented is also in accordance with the genomic sequence for the sheep GH gene that has been reported.
