The olfactory receptor OR2A1 is a member of the G protein-coupled receptor (GPCR) family, encoded by the OR2A1 gene in humans. It is primarily associated with the olfactory system, where it plays a role in detecting and transducing odorant signals. As a class II olfactory receptor, OR2A1 is expressed in the nasal epithelium and binds to specific volatile molecules, initiating signal transduction cascades that contribute to the perception of smell. However, its exact ligands and physiological roles remain partially characterized. Structurally, it features seven transmembrane domains, typical of GPCRs, with extracellular loops involved in odorant recognition.
Recombinant OR2A1 protein is produced using expression systems like mammalian cells or bacteria, often tagged for purification and detection. Studying this protein aids in unraveling olfactory mechanisms, receptor-ligand interactions, and signaling pathways. It also holds potential for applications in biosensors, fragrances, or therapeutic research, as olfactory receptors are found in non-olfactory tissues, suggesting broader physiological functions. Challenges in its study include low natural abundance, complex membrane protein folding, and difficulties in functional expression *in vitro*. Advances in structural biology and recombinant technology continue to refine our understanding of OR2A1’s role in sensory and systemic processes.
