OR8H1, a member of the olfactory receptor (OR) family, is a G protein-coupled receptor (GPCR) primarily associated with odorant detection in humans. These receptors are expressed in olfactory sensory neurons, where they bind volatile odor molecules, initiating signal transduction pathways that translate chemical stimuli into neural signals for smell perception. Although the human genome contains ~400 functional OR genes, the specific ligands and biological roles of many, including OR8H1, remain poorly characterized. OR8H1 is localized on chromosome 11 and shares structural features with other ORs, including seven transmembrane domains and extracellular loops critical for ligand interaction.
Recombinant OR8H1 protein is produced using heterologous expression systems (e.g., mammalian or insect cells) to study its biophysical properties, ligand specificity, and activation mechanisms. Challenges in OR8H1 recombinant production include low expression levels, membrane protein instability, and the need for lipid bilayer mimicry in purification. Current research focuses on de-orphaning OR8H1 through high-throughput ligand screening and structural studies using cryo-EM or X-ray crystallography. Emerging evidence suggests potential non-olfactory roles for ORs in tissues like brain, heart, and skin, implying broader physiological relevance. Characterization of OR8H1 may advance understanding of chemosensory disorders, neurodegenerative diseases linked to olfaction deficits, and therapeutic targeting of GPCR signaling pathways. Additionally, engineered OR8H1 variants are being explored for biosensor applications in environmental or food quality monitoring.
