26106044 MRGX2 is related to nociception, adrenal gland secretion and mast cell degranulation. (Review)
24954276 contributes to larger and longer lasting wheal reactions to intradermally injected neuropeptides in patients with chronic urticaria
23698749 Ectopic expression of MrgX2 in rat basophilic leukemia RBL-2H3 cells and murine bone marrow mast cells renders these cells responsive to human beta-defensin for degranulation.
22069323 identified MrgX2 as a novel G protein-coupled receptor for the antibacterial peptide LL-37 and demonstrated that unlike most G protein-coupled receptors it is resistant to agonist-induced receptor phosphorylation, desensitization, and internalization.
18636314 Mas, MrgD, and MRG mediated Ang IV-stimulated AA release that was highest for Mas. While Ang III activated Mas and MrgX2, Ang II stimulated AA release via Mas and MRG.
15862286 MRGX2 amino acid substitutions may alter the interactions between MRGX2 protein and its ligand, thus, potentially led to adaptive changes of the pain-perception-related nervous system during human evolution.
12915402 cortistatin-14 shown to be a high affinity ligand for G protein coupled receptor MrgX2 which is expressed in dorsal root ganglion
