| Abstract: | To clone a new porcine HK2 gene and analysis its biological function, the cDNA sequences of porcine HK2 were amplified by in silico cloning, which primers designed based on the reported cDNA sequences of human and mouse HK2 gene. The results of sequencing showed we have obtained a complete 2754bp coding sequence of pig HK2 gene which encodes a 917 amino acid protein. The estimated biological character of the HK2 protein. Alignment its cDNA sequence analysis revealed that the sequence shares 90% and 87% homology with that of its human, mouse counterparts, respectively; the deduced protein sequence shares 96% and 94% homology with that of its human, mouse counterparts, Based on HK2 gene cDNA sequence of human and mouse. Its physical and chemical characters were analyzed and its protein structure was predicted by bioinformatic methods and software. Obtain of the basic information and contrast analysis of porcine HK2 gene In our study will play an important role on further study of its structure, function and express regulation. |
