Mas-Related G Protein Coupled Receptor Agonists

Mas-related G protein-coupled receptors (MRGPRs) are a family of orphan GPCRs, subdivided into nine separate subfamilies (A-H and X). They are found in mammalian species, with families A, B, C and H present only in rodents, the X subfamily only in primates, including humans, and families D to G conserved across mammalian species. The MRGPRX family consists of four distinct receptors: MRGPRX1 was previously known as sensory neuron-specific receptor (SNSR) 4 and MRGPRX3 was previously named SNSR1.
