G-Protein Coupled Receptor 103 (GPR103) Antibody

Background

QRFPR is a G protein-coupled receptor (GPCR) activated by pyroglutamylated RFamide peptides, a family of neuropeptides that play a role in regulating physiological processes such as pain modulation, feeding behavior, and hormone secretion. QRFPR primarily couples to Gq proteins, stimulating phospholipase C (PLC) and increasing intracellular calcium, leading to downstream cellular responses. It is expressed in the central nervous system, particularly in regions involved in appetite control and reward systems, as well as in peripheral tissues involved in hormone regulation. QRFPR is involved in modulating sensory processing, specifically in nociception, by influencing pain pathways. Dysregulation of QRFPR signaling is implicated in disorders related to metabolism and pain. This receptor's unique role in mediating these processes makes it a potential target for therapeutic interventions aimed at treating pain and metabolic disorders.
