The Giant Panda is an endangered and valuable gene pool in genetic, its important functional gene POLR2H encodes an essential shared peptide H of RNA polymerases. The genomic DNA and cDNA sequences were cloned successfully for the first time from the Giant Panda (Ailuropoda melanoleuca) adopting touchdown-PCR and reverse transcription polymerase chain reaction (RT-PCR), respectively. The length of the genomic sequence of the Giant Panda is 3,285 bp, including five exons and four introns. The cDNA fragment cloned is 509 bp in length, containing an open reading frame of 453 bp encoding 150 amino acids. Alignment analysis indicated that both the cDNA and its deduced amino acid sequence were highly conserved. Protein structure prediction showed that there was one protein kinase C phosphorylation site, four casein kinase II phosphorylation sites and one amidation site in the POLR2H protein, further shaping advanced protein structure. The cDNA cloned was expressed in Escherichia coli, which indicated that POLR2H fusion with the N-terminally His-tagged form brought about the accumulation of an expected 20.5 kDa polypeptide in line with the predicted protein. On the basis of what has already been achieved in this study, further deep-in research will be conducted, which has great value in theory and practical significance.
