The olfactory receptor family 9 subfamily G member 1 (OR9G1) is a class A G protein-coupled receptor (GPCR) primarily associated with the olfactory system, where it facilitates the detection and discrimination of odorant molecules. As part of the largest mammalian gene family, olfactory receptors (ORs) are transmembrane proteins characterized by seven α-helical domains, extracellular ligand-binding regions, and intracellular signaling domains. OR9G1, encoded by the OR9G1 gene on chromosome 11 in humans, is expressed in olfactory sensory neurons and binds to specific odorants, triggering intracellular cAMP-mediated signaling cascades via G-protein activation. Beyond its role in olfaction, emerging studies suggest ectopic expression of OR9G1 in non-chemosensory tissues (e.g., brain, kidney), hinting at potential non-canonical functions in cellular communication or metabolic regulation. Recombinant OR9G1 protein, typically produced in heterologous systems like HEK293 or insect cells, enables structural-functional studies, ligand screening, and mechanistic exploration of its physiological roles. Its recombinant form retains native conformation and activity, making it valuable for drug discovery targeting OR-related disorders. However, detailed ligand specificity and downstream pathways remain under investigation, reflecting broader challenges in decoding the complex OR interactome.
