摘要: 本研究采用PCR-SSCP方法对陕北白绒山羊、太行黑山羊及南疆绒山羊的角蛋白辅助蛋白(keratin-associated proteins,KAP)7基因进行遗传多态性研究。结果显示,KAP7基因在3个山羊品种中有多态性,有AA和AB 2种基因型,AA基因型均为其优势基因型。测序结果发现,KAP7基因在129 bp处存在C→G的突变,突变的位置位于5'调控区。

Abstract: The polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) was used to detect the polymorphism of keratin associated protein 7 (KAP7) in Shanbei White cashmere goat,Taihang Black goat and Nanjiang White cashmere goat. The results showed that the KAP7 presented AA and AB genetypes in these three breeds,AA genetype was the dominant genetypes. The PCR production of different genotype of KAP7 were purified and sequnenced. One mutation,129 bp(C→G) was found in KAP7. This mutation site was in 5' regulatory region.

Key words: KAP7 gene; PCR-SSCP; Shanbei White cashmere goat; Taihang Black goat; Nanjiang White cashmere goat
