OR9Q1 アクチベーター

OR9I1 can initiate the olfactory signaling process through a variety of molecular interactions. When benzaldehyde, with its characteristic almond-like scent, comes into contact with OR9I1, it binds to the receptor, inducing a conformational change that leads to the activation of the receptor. Similarly, eugenol, which imparts a spicy, clove-like aroma, interacts with OR9I1 by binding to it and initiating a cascade of intracellular events that result in signal transduction. This process is not unique to these compounds, as isoamyl acetate, known for its banana-like fragrance, and 2-phenylethanol, with a floral scent, also engage with OR9I1 in the same manner, triggering the signaling pathway that allows the perception of their respective odors.

Limonene, another activator of OR9I1, carries a citrus scent and activates the receptor, which then signals the brain to recognize the citrus aroma. In the same vein, methyl salicylate interacts with OR9I1 to produce the perception of its minty, wintergreen scent. Anethole, hexanal, and α-pinene also function as ligands for OR9I1, with anethole producing a licorice-like aroma, hexanal contributing a grassy odor, and α-pinene adding a woody, pine-like scent through the activation of OR9I1. Citral, ethyl vanillin, and geraniol further expand the spectrum of scents conveyed through OR9I1 activation, with citral offering a lemon scent, ethyl vanillin providing a sweet, vanilla-like fragrance, and geraniol contributing a rose-like scent, all through their interaction and activation of the OR9I1 receptor, highlighting the diverse range of odorous molecules that can be detected through this single olfactory receptor.
