Abstract: In order to clone the phosphotyrosine interaction domain containing 1(PID1) gene of Luchuan pig,a pair of special primers was designed according to released sequence of Laiwu pig PID1 gene in GenBank.The PID1 gene was amplified by RT-PCR,its gene sequence characteristics and protein structure was systemically analyzed by bioinformatics techniques.The results showed that the cloned PID1 gene fragment included a 654 bp whole length CDS (coding 217 amino acids).The sequence multi-aligned results showed that Luchuan pig shared 99.08%,87.61%,93.88%,93.58%,90.06%,83.79%,66.94%,66.52% and 60.09% of similar nucleotide sequence with that of Laiwu pig,Bos,Macaca,Homos,Mus,Gallus,Rattus,Danio retio and Xenopus, respectively.The phylogenetic tree indicated that PID1 gene was highly conserved in the process of evolution of different species.The cloning and analysis of PID1 gene provided an important foundation for further study regulation mechanism of PID1 gene in Luchuan pig.
