**Background of Recombinant Human OR2M4 Protein**
The human olfactory receptor OR2M4. a member of the G protein-coupled receptor (GPCR) family, is encoded by the *OR2M4* gene located on chromosome 1. While initially identified as a mediator of olfaction, OR2M4 has garnered attention for its potential roles beyond sensory perception. Unlike many olfactory receptors, OR2M4 exhibits a broader expression profile, with detectable levels in non-olfactory tissues such as the gastrointestinal tract, lungs, and prostate, suggesting possible physiological or pathological functions unrelated to smell.
Recombinant OR2M4 protein is produced via genetic engineering, typically using mammalian or bacterial expression systems, to enable functional and structural studies. This protein retains the seven-transmembrane domain architecture characteristic of GPCRs, critical for ligand binding and signal transduction. Studies have linked OR2M4 to specific odorant recognition, including the detection of sulfur-containing compounds like dimethyl trisulfide (a marker of spoiled food). However, emerging research implicates OR2M4 in disease contexts, such as cancer progression, where its aberrant expression may influence cell proliferation or metabolic pathways.
Characterizing recombinant OR2M4 aids in deciphering its ligand specificity, activation mechanisms, and downstream signaling, which could inform therapeutic targeting or biomarker development. Ongoing investigations continue to unravel its dual roles in chemosensation and cellular physiology.
