Olfactory receptor 1J1 (OR1J1) is a member of the olfactory receptor (OR) family, which constitutes the largest subset of G protein-coupled receptors (GPCRs) in humans. These receptors are primarily responsible for detecting odorants and initiating signal transduction pathways that translate chemical stimuli into olfactory perception. OR1J1. encoded by the OR1J1 gene, is expressed in olfactory sensory neurons within the nasal epithelium. Unlike some ORs with broad ligand specificity, OR1J1 is speculated to recognize distinct odorant molecules, though its exact ligands and activation mechanisms remain under investigation.
Recombinant OR1J1 protein is artificially produced using heterologous expression systems (e.g., bacterial, yeast, or mammalian cells) to study its structural and functional properties. Generating functional recombinant OR1J1 is challenging due to the inherent difficulty in expressing and stabilizing transmembrane GPCRs in vitro. Researchers often employ detergent solubilization or lipid-based systems to maintain its native conformation.
Recent studies explore OR1J1’s potential roles beyond olfaction, including interactions with metabolic pathways or disease-associated processes. Its recombinant form serves as a tool for high-throughput screening of odorant ligands, structure-function analyses, and exploring OR-related therapeutic targets. However, comprehensive characterization of OR1J1 remains limited, reflecting broader challenges in deciphering the complexity of human olfaction at the molecular level.
