GPR75 Recombinant Rabbit mAb (S-5035)

GPR75, or G protein-coupled receptor 75, is an orphan G protein-coupled receptor primarily expressed in the brain, particularly within the hypothalamus, where it plays a critical role in regulating energy homeostasis and body weight. Recent genetic studies have identified GPR75 as a significant protective factor against obesity, demonstrating that loss-of-function mutations or knockout of this receptor in mice leads to resistance to diet-induced obesity, improved insulin sensitivity, and increased energy expenditure without affecting food intake. Mechanistically, GPR75 is believed to interact with signaling pathways involving the melanocortin system and may respond to specific lipid ligands, thereby influencing neuronal activity in appetite-regulating centers. Due to its profound impact on metabolic regulation and the strong association between its inhibition and leanness in both animal models and human population genetics, GPR75 has emerged as a highly promising therapeutic target for the development of novel anti-obesity and antidiabetic drugs.
