OR8H3 can initiate a cascade of intracellular events leading to its activation. Isoproterenol, a synthetic beta-adrenergic agonist, engages with its corresponding receptors, triggering a signaling pathway that results in the activation of adenylate cyclase. This enzyme catalyzes the conversion of ATP to cAMP, a secondary messenger that plays a pivotal role in cellular signaling. The accumulation of cAMP in the cytoplasm can activate protein kinase A (PKA), which is capable of phosphorylating a variety of cellular proteins, including OR8H3. Similarly, forskolin, a diterpene, acts directly on adenylate cyclase, bypassing receptor engagement and leading to an upsurge in cAMP and subsequent activation of PKA, which then can phosphorylate OR8H3. IBMX, meanwhile, prevents the degradation of cAMP by inhibiting phosphodiesterases, thus sustaining PKA in its active form to phosphorylate OR8H3.
Epinephrine and norepinephrine, both catecholamines, stimulate adrenergic receptors, which signal through G proteins to increase adenylate cyclase activity. This elevation in cAMP levels promotes PKA activation, which in turn phosphorylates OR8H3. Histamine, interacting with H2 receptors, and dopamine, through dopamine receptors, also enhance adenylate cyclase activity, subsequently raising cAMP levels and activating PKA, leading to the phosphorylation of OR8H3. Adenosine and PGE2, by binding to their respective receptors, activate adenylate cyclase, which increases cAMP and activates PKA, resulting in OR8H3 phosphorylation. Similarly, PACAP and glucagon, by engaging with their specific receptors, stimulate adenylate cyclase, leading to a rise in cAMP and PKA activation, which then can phosphorylate OR8H3. Lastly, cholera toxin, by permanently activating the Gs alpha subunit, leads to continuous activation of adenylate cyclase, causing chronic elevation of cAMP levels and sustained PKA activation, which subsequently phosphorylates OR8H3.
