Olfactory receptor 1F1 (OR1F1), a member of the olfactory receptor (OR) family, is a class A G protein-coupled receptor (GPCR) primarily associated with olfactory sensory functions. These receptors detect odorant molecules in the nasal epithelium, initiating signal transduction via G protein-mediated pathways (e.g., cAMP signaling) to transmit smell signals to the brain. OR1F1 is encoded by the OR1F1 gene located on human chromosome 9. While its exact ligands remain uncharacterized, it shares structural features with other ORs, including seven transmembrane domains and ligand-binding pockets. Interestingly, OR1F1 expression is not restricted to olfactory tissues; low levels have been detected in non-olfactory organs (e.g., lung, testis), suggesting potential roles in chemosensation or non-canonical physiological processes.
Recombinant OR1F1 protein is typically produced in heterologous systems (e.g., mammalian, insect cells) to study its structure, ligand specificity, and signaling mechanisms. Its recombinant expression faces challenges due to ORs' inherent instability and membrane localization requirements. Advances in solubilization techniques (e.g., nanodiscs, detergent optimization) and structural biology tools (cryo-EM, X-ray crystallography) are enabling deeper insights into OR1F1’s activation mechanisms. Current research focuses on deorphaning OR1F1 (identifying its ligands) and exploring its therapeutic potential, particularly in diseases linked to olfactory dysfunction or ectopic OR expression. However, functional studies remain limited compared to other sensory receptors, highlighting the need for further characterization.
