Molecular characterization and tissue expression profile analysis of the porcine JAZF1 gene.
A recent study indicated that the JAZF1 gene was related to lipid metabolism by regulating the level of gene expression in humans and mice. In order to investigate whether JAZF1 gene expression was associated with fat deposition in pig, we cloned the full-coding region of the JAZF1 gene (GenBank accession No. KF307636) from porcine longissimus dorsi. Results showed that the open reading frame of JAZF1 covered 732 bp and encoded 243 amino acids. Multiple alignment of isoform sequences revealed that the deduced amino acid sequence of JAZF1 had a high degree of sequence similarity to other vertebrates, indicating that it was highly conserved during evolution. Bioinformatic analysis indicated that pig JAZF1 contained 23 phosphorylation sites and 19 glycosyl sites. JAZF1 was predicted to have 3 ZnF-C₂H₂ and 2 low-complexity domains. The JAZF1 mRNA expression pattern indicated that JAZF1 mRNA expression level in the liver was significantly different in 2 divergent breeds (P < 0.05). This article perhaps provided an important experimental basis for further research on the mechanisms of lipid metabolism and fat deposition in pigs.
