However, the information regarding the gene structure, functionality and tissue expression of UTS2/URP receptor remains largely unknown in non-mammalian vertebrates including birds. In this study, using RACE-PCR, we cloned the full-length cDNAs of four chicken UTS2/URP receptors and designated them as cUTS2R1, cUTS2R2, cUTS2R3 and cUTS2R5 respectively, according to their evolutionary origin. The cloned cUTS2R1, cUTS2R2, cUTS2R3 and cUTS2R5 are predicted to encode 7-transmembrane receptors of 382, 343, 331 and 363 amino acids respectively, which show 41-57% amino acid sequence identity with human UTS2R. Using cell-based luciferase reporter assays and Western blot, we demonstrated that chicken UTS2Rs expressed in HEK293 cells could be effectively activated by synthetic chicken UTS2-12, UTS2-17 and URP peptides, and their activation can elevate intracellular calcium concentration and activate MAPK/ERK signaling cascade, indicating that the four UTS2Rs are functional and capable of mediating UTS2/URP actions in chickens. Quantitative real-time PCR revealed that the four receptors are widely, but differentially, expressed in adult chicken tissues, while cUTS2 and cURP are highly expressed in the hindbrain and spinal cord, and moderately/weakly expressed in other tissues examined including the spleen and gonads. Taken together, our data provide first piece of evidence that all four UTS2Rs are functional in an avian species and help to reveal the conserved roles of UTS2R signaling across vertebrates.","claims":[{"public_id":"cl_100ce865c1036d1edb9386da4cdcddff","status":"active","text":"Activation of chicken UTS2Rs elevated intracellular calcium concentration and activated the
