Abstract: The experiment was conducted to clone 5'-flanking region of bovine UCP3 gene to study regulatory mechanism of the specific transcriptional regulation region. The 5'-flanking region of bovine UCP3 gene was amplified with PCR, and then the 1080 bp 5'-flanking promoter sequence was obtained by product purification, ligation, transformation, and sequence comparison. The obtained cloning vector of 5'-flanking region of bovine UCP3 gene was analyzed by the promoter software in this study. The results indicated that there were 6 transcription start sites and 33 potential transcription factor binding promoter region of the gene, the highly conserved region was in -196~+100 bp of the upstream of transcription start sites, which might be conclude that the -200~+1 bp of the upstream of transcription start sites was the core. Comparing bovine with Panthera tigris, Felis catus, Bubalus bubalis, Pantholops hodgsonii, Capra hircus, Ovis aries,the homology of 5'-flanking promoter sequence were 82%, 82%, 98%, 95%, 96% and 98%, respectively. The 1080 bp 5'-flanking region of the bovine UCP3 gene was cloned successfully and the core promoter region was preliminary predicted in the gene.
