The human olfactory receptor OR1J2. belonging to the G protein-coupled receptor (GPCR) superfamily, is a chemosensory protein primarily expressed in olfactory epithelial cells. It plays a critical role in detecting odorant molecules and transducing olfactory signals by interacting with specific volatile compounds. As part of the largest mammalian receptor family (>380 members in humans), OR1J2 shares conserved structural features, including seven transmembrane domains and ligand-binding pockets, but exhibits distinct ligand specificity.
Recombinant OR1J2 protein is typically produced using heterologous expression systems (e.g., HEK293 or insect cells) with engineered tags (such as His-tag) for purification and detection. Its recombinant form enables structural studies (e.g., X-ray crystallography), functional characterization of ligand-receptor interactions, and high-throughput screening for odorant identification. Emerging research suggests potential extra-nasal expression in tissues like lungs and brain, hinting at broader physiological roles beyond smell perception, including cellular regulation or disease pathways.
Current challenges involve stabilizing the recombinant protein due to GPCR complexity and identifying its natural ligands. OR1J2 studies contribute to understanding odor coding mechanisms and developing biosensors or therapeutic targets for GPCR-related disorders. (Word count: 198)
