Data Sheet
Background: MRGX1 (MAS-related GPR member X1) is also known as SNSR4 (sensory neuron-specific G-protein-coupled receptor 4). It can be potently activated by enkephalins including BAM22 and BAM(8-22). MRGX1 receptor is expressed solely in small diameter primary sensory neurons. This restricted expression pattern is of considerable therapeutic interest because small nociceptors transmit chronic pain messages.
Application: Functional assays
