Activation of the GPCR GPR120 by free fatty acids has been reported to cause GLP-1 release in rodent intestine. One genetic sequence was reported for rodents, while two sequences were reported for human GPR120, BC101175 and NM_181745. A 1086 base pair sequence cloned from cynomolgus monkey colon cDNA has 85.1% and 83.4% homology with the mouse and rat GPR120 sequences, and 97.5% homology with the human BC101175 sequence. No splice variants of the cynomolgus monkey GPR120 receptor were found. Eight non-synonymous cSNPs were discovered with frequencies less than 4% in monkey samples tested. Real-time PCR demonstrated that, like the human, the highest GPR120 expression in cynomolgus monkey is in lung and colon. Studies measuring intracellular calcium release produced by free fatty acids and the small molecule GPR120 agonist GW9508 in cells expressing the cynomolgus monkey GPR120 receptor were compared to those expressing the human BC101175 splice variant. Long-chain free fatty acids produced the greatest response in cynomolgus monkey GPR120-expressing cells. GW9508 had similar efficacy at the cynomolgus monkey and at the BC101175 human GPR120 receptors. The cynomolgus monkey and the human GPR120 (BC101175) receptors have similar sequences and pharmacology. The possible significance of the alternate splice variant in human is discussed.
