山羊肌生成抑制素基因完全编码序列分析

摘要

In this experiment,exon 1,2,3 and part of introns of goat MSTN were cloned and sequenced. Result showed that goat MSTN exon was 1 128 bp in length, which encoded 375 amino acids. Compared with other mammals, the similarity of MSTN gene were 90％ above, which had the highest divergence in exon 1, and the lowest divergence in exon 3, either in coding sequence or in coding amino acid.%文章对山羊肌生成抑制素基因(MSTN)外显子1、2、3及部分内含子扩增后克隆测序,得出:山羊肌生成抑制素基因外显子全长1 128 bp,编码375个氨基酸,并与其它7种哺乳动物比较发现,各物种MSTN基因同源性在90%以上,编码序列及编码氨基酸的差异,外显子1差异最大,外显子3差异最小.
