Primary structure and tissue distribution of GPR39 messenger ribonucleic acid in Japanese quail, Coturnix japonica.

Abstract

It has been found that GPR39 is an orphan receptor that belongs to the family of G protein-coupled receptors. In mammals, GPR39 has been shown to be involved in the regulation of gastrointestinal and metabolic function. In this study, we performed cDNA cloning for GPR39 in Japanese quail and characterized the tissue expression profiles of its mRNA. The cDNA encoded 462 amino acids, showing very high sequence homology to chicken GPR39 (95.5%) and moderate homology to mouse (64.7%), rat (63.7%), and human (59.9%) GPR39. Real-time PCR analysis revealed that GPR39 mRNA is expressed at high levels in the digestive tissues such as stomach, duodenum, jejunum, ileum, cecum, and colon and rectum and at moderate levels in the oviduct including infundibulum, magnum, isthmus, and uterus. These findings suggest that GPR39 may be involved in gastrointestinal and oviductal functions in Japanese quail.
