GeneCards Summary for MRGPRX2 Gene
MRGPRX2 (MAS-Related GPR, Member X2) is a Protein Coding gene. GO annotations related to this gene include G-protein coupled receptor activity and mast cell secretagogue receptor activity. An important paralog of this gene is MRGPRX4.
UniProtKB/Swiss-Prot for MRGPRX2 Gene
Mast cell-specific receptor for basic secretagogues, i.e. cationic amphiphilic drugs, as well as endo- or exogenous peptides, consisting of a basic head group and a hydrophobic core (PubMed:25517090). Recognizes and binds small molecules containing a cyclized tetrahydroisoquinoline (THIQ), such as non-steroidal neuromuscular blocking drugs (NMBDs), including tubocurarine and atracurium. In response to these compounds, mediates pseudo-allergic reactions characterized by histamine release, inflammation and airway contraction (By similarity). Acts as a receptor for a number of other ligands, including peptides and alkaloids, such as cortistatin-14, proadrenomedullin N-terminal peptides PAMP-12 and, at lower extent, PAMP-20, antibacterial protein LL-37, PMX-53 peptide, beta-defensins, and complanadine A.
