OR5T3, a member of the olfactory receptor (OR) family, is a class A G protein-coupled receptor (GPCR) primarily associated with odorant detection. Located on chromosome 11 in humans, OR5T3 is expressed in olfactory sensory neurons, where it contributes to recognizing specific odorant molecules. However, its precise endogenous ligands and physiological roles remain partially characterized. Recent studies suggest OR5T3 may also be ectopically expressed in non-olfactory tissues, implying potential secondary functions in cellular signaling or disease pathways.
Recombinant OR5T3 protein is typically produced via heterologous expression systems like HEK293 or insect cells, enabling structural and functional studies. As a GPCR, it features seven transmembrane domains and interacts with G-proteins to trigger intracellular signaling cascades. Challenges in OR5T3 production include proper membrane localization and post-translational modifications critical for ligand-binding activity. Structural resolution efforts (e.g., cryo-EM) aim to elucidate its activation mechanisms and binding pockets.
Research focuses on OR5T3's role in chemosensation, potential therapeutic targets for smell disorders, and possible links to diseases like cancer. Its recombinant form is valuable for high-throughput ligand screening and biosensor development. Unlike broad-spectrum ORs, OR5T3 appears selective for specific hydrophobic compounds, though exact specificity profiles require further validation.
