Specificity Protein
Primate-specific Mas-related G protein-coupled receptor-X1 (MRGPR-X1) is highly enriched in dorsal root ganglia (DRG) neurones as well as in connective tissue mast cells (CTMC) and the leukaemia-derived human mast cell line (LAD)-2. MRGPR-X1 activation induces acute pain and therefore represents a promising target for future pain therapy.

MRGPR-X1 is activated by bovine adrenal medulla peptide-8-22 (BAM 8–22) which is cleaved from pro-enkephalin by pro-hormone convertases. Unlike most if not all Gq-coupled receptors MRGPR-X1 does not undergo agonist-promoted endocytosis.
