The recombinant human OR2J1 protein is a genetically engineered form of the olfactory receptor 2J1. a member of the G protein-coupled receptor (GPCR) superfamily. As part of the olfactory receptor (OR) family, OR2J1 is primarily associated with odorant detection, playing a role in recognizing specific volatile chemical molecules in the olfactory epithelium. Olfactory receptors like OR2J1 mediate signal transduction by binding odorants, activating downstream G-protein pathways, and triggering neuronal responses. However, OR2J1's exact endogenous ligands and physiological roles beyond olfaction remain under investigation.
Recombinant OR2J1 is typically expressed in heterologous systems (e.g., HEK293 cells or insect cell lines) to overcome challenges in studying native ORs, which are membrane-bound and low in abundance. This engineered protein often incorporates solubility-enhancing tags (e.g., GFP or His-tags) and may utilize modified constructs to improve expression and purification yields. Its recombinant form enables structural-functional studies, including ligand-binding assays, receptor activation mechanisms, and interactions with olfactory signaling components.
Current research focuses on deorphanizing OR2J1 by identifying its activating odorants and exploring potential non-olfactory functions, such as roles in tissue-specific signaling. Studies also investigate its genetic variations linked to smell disorders or metabolic conditions. Recombinant OR2J1 serves as a tool for developing biosensors or screening platforms for fragrance-related applications, while emerging evidence suggests possible connections to diseases like cancer, broadening its biomedical relevance beyond sensory biology.
