Researchers Identify Key Protein Regulating Appetite and Weight
Source: medicalxpress.com Key Points: MRAP2 controls appetite via MC4R. Target for obesity treatment. International research breakthrough. Berlin, Oct. 6—Researchers at Leipzig University and Charité – Universitätsmedizin Berlin have identified a key mechanism showing how the MRAP2 protein regulates appetite and body weight. The discovery explains how a protein called MRAP2 (melanocortin 2 receptor accessory protein 2) influences another brain receptor, MC4R (melanocortin-4 receptor), which plays a central role in controlling appetite and energy balance. The findings were published in Nature Communications. The study was conducted under the Collaborative Research Centre (CRC) 1423 – Structural Dynamics of GPCR Activation and Signaling. Scientists found that MRAP2 directly affects how MC4R functions and is transported within cells, providing new insights into how the body regulates food intake. This discovery explains in detail how the MRAP2 protein regulates appetite. MC4R is a r...
