Abstract: Caveolins, a class ofprincipal proteins forming the structure of caveolae in plasmalemma, were encoded by caveolins gene family. Caveolin-1 gene is a member of caveolins gene family. In the present study, a full-length of 2605 bp caveolin-1 cDNA sequence in Columba livia domestica, which included a 537 bp complete ORF encoding a 178 amino acids long putative peptide, were obtained by using RT-PCR and RACE technique. The Columba livia domestica caveolin-1CDS shared 80.1% − 93.4% homology with Bos taurus, Canis lupus familiaris, Gallus gallus and Rattus norvegicus. Meanwhile, the putative amino acid sequence of Columba livia domestica caveolin-1 shared 85.4% − 97.2% homology with the above species. The semi-quantity RT-PCR revealed that Caveolin-1expressions were detectable in all the Columba livia domestica tissues and the expressional level of caveolin-1 gene was high in adipose, medium in various muscles, low in liver. These results demonstrated that Caveolin-1 gene was potentially involved in some metabolic pathways in adipose and muscle.
