**Background of Recombinant Human OR5R1 Protein**
OR5R1 (Olfactory Receptor Family 5 Subfamily R Member 1) is a G protein-coupled receptor (GPCR) primarily associated with olfactory signaling. As part of the olfactory receptor (OR) family, it plays a role in detecting odorant molecules by binding specific ligands, which triggers intracellular signaling cascades via G-protein activation. ORs, including OR5R1, are characterized by seven transmembrane domains and exhibit high ligand specificity, contributing to the vast odor discrimination capacity in humans.
The recombinant form of OR5R1 is produced in heterologous expression systems (e.g., mammalian or insect cells) using genetic engineering, enabling controlled study of its structure and function. Recombinant production bypasses challenges of low native expression in biological tissues, allowing researchers to investigate OR5R1’s ligand-binding profiles, activation mechanisms, and downstream signaling pathways.
Though OR5R1’s exact physiological ligands remain under investigation, it is hypothesized to interact with specific odorants or signaling molecules. Beyond olfaction, ORs are increasingly studied for roles in non-olfactory tissues, including the brain, lungs, and gut, suggesting potential involvement in metabolic regulation, immune responses, or disease pathways. Recombinant OR5R1 serves as a critical tool for deciphering these roles, aiding drug discovery and advancing understanding of GPCR biology.
