Abstract: Abstract:Melanocortin receptor-4(MC4R)gene in mink was cloned and sequenced,in order to provide theoretical foundation for further research of the corelevantion of MC4R gene in mink and fat traits,and location. MC4R gene of mink was amplified using particular primers,cloned by polymerase chain reaction (PCR) method and sequenced,and spliced by using DNAMAN. The length of MC4R gene in mink was 816 bp. The sequences had been sent to GenBank and registered. Comparison of the fragment sequence with that of other mammal animals MC4R gene was carried out through BLAST in GenBank,the results showed that the homologies of the nucleotide sequence with river otter,dog,fox,panda,river horse,boar,goat,human and rat were 89% to 95%,MC4R gene of mink was successfully cloned in this study,indicating it was quite conservative among species.
