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. 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. 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.

Low levels of MRGPRX2 were detected in non-asthma lung mast cells, but its expression was significantly up-regulated in asthma lung mast cells.PMID:29295703
the present study demonstrates that FceRI and MRGPRX2 function can be inversely regulated by SCF in an acute scenario, suggesting that the signaling requirements differ profoundly between the routes.PMID:28859248
The authors discuss the possibility that MRGPRX2 responds to various as-yet-unidentified endogenous ligands that have specific characteristics, and propose that MRGPRX2 plays an important role in regulating inflammatory responses to endogenous harmful stimuli, such as protein breakdown products released from damaged or dying cells.PMID:29484687
these peptides are identified as fragments of albumin. The isolated fragments activate MRGPRX2 and degranulate MRGPRX2 expressing LAD 2 cells in dose-dependent manner. The isolated basic peptides generated from human albumin are able to degranulate mast cells via the MRGPRX2.PMID:28844982
The results showed a kind of mechanism that sinomenine-induced anaphylactoid reactions were mediated by MRGPRX2 via activating PLC molecular signaling pathways to provoke mast cells Ca(2+) mobilization and degranulation.PMID:28987593
