Abstract: A pair of pecific primer was designed using Primer 3.0 software to amplify the sequence of KIFI gene from goat genomic DNA. The KIFI was cloned into pGEM-T vector,positive colonies were sequenced and digested by restriction endonuclease after transforming. The results showed that the sequence length was 472 bp (No.GQ988385),including Exon 1,part of 5′UTR and part of Intron 1 sequence of goat KIFI Gene,Exon 1 sequence coding for polypeptide contains 116 amino acid. Which shared 98%,90%,90%,88% and 84% homology with the sequences of sheep,cattle,horse,human and house mouse. Therefore,cloning of goat KIFI gene could be a basis for the further study on polymorphism and correlation on cashmere trait.
