摘要 为了研究硬脂酰辅酶A去饱和酶(SCD)基因对肌间脂肪组织三酰甘油形成的影响,试验采用克隆隆林山羊SCD基因CDS区序列并进行序列分析的方法,根据Gen Bank中收录的西农萨能羊SCD序列设计引物并进行PCR扩增及克隆测序,利用在线生物信息学软件分析SCD蛋白的序列特性,分析不同物种间SCD基因的进化关系及三级结构,从而预测隆林山羊SCD基因的功能。结果表明:隆林山羊SCD基因CDS区序列全长1 080 bp,由4个外显子组成,编码359个氨基酸,与牛、绵羊、人的氨基酸相似度分别为94.2%、98.3%、83.8%,并与牛和人具有相似的三级结构。系统进化树显示,隆林山羊与绵羊和牛具有较近的亲缘关系,而与鸡的亲缘关系较远。
