**Background of Recombinant Human OR12D2 Protein**
The olfactory receptor OR12D2. encoded by the *OR12D2* gene, belongs to the class II olfactory receptor family within the G protein-coupled receptor (GPCR) superfamily. Olfactory receptors (ORs) are critical for detecting odorant molecules, enabling the sense of smell. ORs recognize diverse chemical structures, translating extracellular signals into intracellular responses via cAMP-mediated pathways. OR12D2 is predominantly expressed in olfactory sensory neurons, though extra-nasal expression has been reported in tissues like the testes, suggesting non-olfactory roles.
Recombinant OR12D2 protein is produced in vitro using heterologous expression systems (e.g., HEK293. insect cells) to enable functional and structural studies. Generating active OR12D2 is challenging due to the complex membrane-bound nature of GPCRs, often requiring lipid-embedded environments and chaperone proteins for proper folding. Tags (e.g., GFP, His-tag) are typically added for purification and detection.
Research focuses on identifying OR12D2’s ligand specificity, activation mechanisms, and potential therapeutic applications. ORs are explored as targets for diseases (e.g., metabolic disorders, cancer) and for biosensor development. Additionally, genetic variations in *OR12D2* may influence individual smell perception, offering insights into human olfaction diversity. Recombinant OR12D2 serves as a key tool to decipher olfactory coding and receptor-ligand dynamics, bridging gaps in sensory biology and translational research.
