Cloning of the BPLA(2) Gene from Agkistrodon halys Pallas.
First strand cDNA synthesis was primed with synthetic oligonucleotide from total RNA extracted from the gland of the snake Agkistrodon halys Pallas. The pro-BPLA(2) gene was then amplified by PCR and cloned into the pBS-ks vector. Its nucleotide sequence has been determined by analyzing the DNA sequence of three colonies containing the pro-BPLA(2) gene. The deduced amino acid sequence consists of 138 amino acids and agrees with the partly known amino acid sequence except for seven amino acid residues. The successful cloning of the BPLA(2) gene not only has made the determination of its total amino acid sequence possible, but also provided a good basis for further research work in the protein engineering of functional peptides from snakes.
