OR10A3 Activators

OR10A3 include a variety of compounds typically recognized by their fragrant nature, which engage the olfactory receptor proteins and initiate signal transduction pathways leading to activation. Citronellal, a terpenoid with a lemon-like scent, binds to the OR10A3 receptor site, causing a conformational change that triggers the receptor. Similarly, eugenol, with its clove scent, and geraniol, with a rose-like aroma, both serve as ligands for olfactory receptors such as OR10A3. By directly interacting with the receptor's ligand-binding domain, these compounds induce activation by altering the receptor's structure to initiate an intracellular response.

Additional activators include (-)-carvone, which presents a minty aroma, and is known to activate olfactory receptors by binding to their specific domains, suggesting direct activation of OR10A3. Isoeugenol, which shares a similar structure with eugenol, also binds to and activates the receptor. Methyl salicylate, with a wintergreen scent, and phenethyl alcohol, which offers a floral fragrance, both activate olfactory receptors by direct interaction, indicating a similar activation mechanism for OR10A3. Terpenes such as alpha-pinene and beta-ionone, which are characterized by woody and violet-like scents respectively, are recognized as activators for various olfactory receptors, including OR10A3, through ligand-receptor binding interactions. Limonene and linalool, both with citrus and floral notes respectively, activate OR10A3 through direct binding to the receptor, while alpha-terpineol, with its lilac aroma, similarly binds to and activates olfactory receptors, suggesting a comparable activation pathway for OR10A3. These chemicals collectively activate OR10A3 by engaging with its ligand-binding site, causing an activation cascade that is characteristic of olfactory signal transduction.
