摘　　要：本研究采用同源克隆技术克隆鳜鱼红肌肌球蛋白重链1(sMyHC1)基因cDNA序列,其总长为5 940 bp。经生物信息学分析表明,鳜鱼sMyHC1基因cDNA编码区全长5 823 bp,总共编码1940个氨基酸。序列分析表明,鳜鱼MyHC1基因cDNA存在3个ATP结合位点、3个actin结合位点、1个ELC结合位点、1个RLC结合位点和2个Loop环。对鳜鱼sMyHC1基因进行成鱼红、白肌表达分析表明,其在红肌和心肌中的表达量显著高于白肌。研究结果为深入研究鳜鱼肌纤维分型及鳜鱼肉质研究提供可靠的实验数据和理论基础。The slow Myosin heavy chain 1 of Mandarin fish was cloned by Homologous cloning technolo gy. The slow Myosin heavy chain 1 gene is 5 823 bp in length and encodes 1 940 amino acids. Sequence a nalysis showed that the slow Myosin heavy chain 1 contains three ATP binding sites,three actin binding sites, one ELC binding site,one RLC binding site and two Loops ring. The expression level in red mus cle was significantly higher than that in white muscle and cardiac muscle. The above results will make contribution to provide reliable experimental data and theoretical basis for the muscle phenotype and the research of meat quility of Siniperca chuatsi.
