Olfactory receptor 1Q1 (OR1Q1), a member of the olfactory receptor (OR) family, is a class A G protein-coupled receptor (GPCR) characterized by its seven transmembrane α-helical structure. Predominantly expressed in olfactory sensory neurons, OR1Q1 binds odorant molecules to initiate signal transduction via G-protein-mediated pathways, converting chemical cues into neural signals for smell perception. Beyond olfaction, emerging studies suggest its ectopic expression in non-chemosensory tissues, including the brain, kidney, and respiratory system, implying potential roles in cellular communication, tissue homeostasis, or disease processes.
Recombinant human OR1Q1 protein is artificially produced using heterologous expression systems (e.g., mammalian cells, insect cells) to study its ligand specificity, activation mechanisms, and downstream signaling. Its structural and functional characterization aids in deciphering odorant-receptor interactions and contributes to the development of biosensors or therapeutic agents targeting OR-related disorders. Challenges include low natural abundance, complex membrane protein folding, and difficulties in identifying physiological ligands. Current research focuses on elucidating its extra-nasal functions, particularly in neuroinflammation, cancer progression, and metabolic regulation. Advances in cryo-EM and computational modeling are accelerating OR1Q1 studies, offering insights into GPCR biology and personalized medicine strategies.
