title: The cloning and sequencing of cervine interleukin 10.
abstract: We report the cloning and sequencing of the cervine interleukin-10 gene. Specific cDNA was amplified by PCR using primers based on the bovine sequence. This was cloned into pGEM 5Zf and several clones were sequenced. The 762 nucleotide product coded for a 179 amino acid protein which was 86% homologous with its bovine and 77% homologous with its human counterparts. There is a strongly hydrophobic signal sequence consisting of the first 20 amino acids and a potential glycosylation site at amino acids 134-136. There are three regions, comprising 34% of the protein, which show complete homology between the cervine, bovine and human sequences. The transcription of the gene was shown by Northern Blotting where a single, 1.8kb, mRNA transcript was detected 4-8 hours after activation of peripheral blood mononuclear cells with mitogen.
