Recombinant human OR8A1 protein is a synthesized form of the odorant receptor 8A1, a member of the G protein-coupled receptor (GPCR) superfamily. Olfactory receptors (ORs), including OR8A1, are primarily expressed in olfactory sensory neurons, where they detect odorant molecules and initiate signal transduction via cAMP or inositol phosphate pathways. As a Class A GPCR, OR8A1 features seven transmembrane α-helices, ligand-binding pockets, and conserved motifs critical for odorant recognition and receptor activation. Produced through heterologous expression systems (e.g., HEK293 or insect cells), recombinant OR8A1 enables studies on its structural and functional properties, often requiring lipid-rich environments or detergents to maintain stability. While its natural ligands remain under investigation, OR8A1 has been implicated in recognizing specific volatile compounds, contributing to odor discrimination. Emerging research explores its potential roles beyond olfaction, including expression in non-olfactory tissues and associations with diseases like cancer. The recombinant protein serves as a tool for deorphaning receptors, screening odorant/receptor interactions, and developing biosensors. Challenges persist in resolving its high-resolution structure and confirming physiological ligands, reflecting broader complexities in OR research. Its study aids in deciphering olfactory coding mechanisms and may inform therapeutic strategies targeting chemosensory pathways.
