OR10H2 Activators

OR10H2 include a diverse set of compounds such as isoamyl acetate, eugenol, benzyl acetate, methyl salicylate, geranyl acetate, citronellol, anisaldehyde, benzaldehyde, heptanal, octanal, nonanal, and decanal. These chemicals interact with OR10H2 via binding to specific sites on the protein, leading to its activation. The binding of a chemical like isoamyl acetate or benzyl acetate to OR10H2 initiates a conformational shift within the protein structure. This change is crucial as it triggers the associated G-protein to exchange GDP for GTP, activating it. Activated G-proteins then go on to influence adenylate cyclase, which increases the conversion of ATP to cyclic AMP (cAMP) within olfactory sensory neurons. The rise in cAMP levels ultimately opens ion channels that result in the depolarization of the neuron, creating an electrical signal that is transmitted to the brain, where it is interpreted as a distinct smell.

OR10H2 for various scent molecules allows for a broad spectrum of odors to be detected and differentiated. For example, eugenol and anisaldehyde, despite having distinct scents, both activate OR10H2 by inducing similar molecular events. Geranyl acetate and citronellol, with their floral and citrus-like odors, respectively, also bind to OR10H2, illustrating the versatility of this receptor in recognizing a range of aromatic structures. The aldehydes, from benzaldehyde to decanal, each with a unique carbon chain length, demonstrate that OR10H2 can accommodate molecules of differing sizes, indicating that the receptor's binding pocket has a certain flexibility. This ability to bind multiple ligands with varying structures and to transduce this binding into a neuronal response underlies the complexity and sophistication of the olfactory system, with OR10H2 playing a pivotal role in translating chemical stimuli into the perception of smell.
