西藏小型猪MSTN基因分子克隆及序列分析
Cloning and sequence analysis of Tibet mini-pig’ s MSTN gene
摘要
Abstract
Objective To amplify the encoding full-length sequence of Tibet mini-pigs myostatin ( MSTN) gene and analysis the sequence by bioinformatics software.Method The RNA of liver tissues from Tibet mini-pig was extracted, and reversely transcribed into cDNA.The gene coding region sequence of myostatin gene was amplified through RT-PCR, and then the purified product of PCR was ligated with a pMD19-T and transferred into the bacterium DH5αfor replication.The positive clones were screened and sequenced. The sequence characters were analyzed by using bioinformatics method and phylogeny evolution tree was constructed with other twelve species.Results The coding redion of MSTN gene was 1128bp, and coded 375 amino acids.The amino acid homology analysis showed that the homology rate of amino acid sequence was 99%.Conclusions Molecular phylogeny evolution indicated that it had a close relation with human, dog, banna minipig, sheep, goat, cattle, horse, chimpanzee, rat, mouse except chick and zebrafish, and the most closely related with banna minipig.关键词
