| Protein Family | G-protein coupled receptor 1 family | ||||||||
| Protein Function |
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity. Mediates Ras activation through G(s)-alpha- and cAMP-mediated signaling. Involved in the regulation of sleep/wake behaviors (PubMed:31473062).

| KEGG Pathway | hsa:5732 | ||||||||
| Protein Family | G-protein coupled receptor 1 family | ||||||||
| Protein Function |
Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(s) proteins that stimulate adenylate cyclase. The subsequent raise in intracellular cAMP is responsible for the relaxing effect of this receptor on smooth muscle.

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | While therapies that target the prostacyclin pathway have been used in combination with diuretics, antihypertensives, or other vasodilators in the management of pulmonary arterial hypertension, caution is recommended if they must be administered concurrently. If these drugs are used together, it is generally recommended that blood pressure be measured more frequently until a stable blood pressure pattern is observed. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their doctor if they experience dizziness, lightheadedness, syncope, orthostatic hypotension, or tachycardia. | ||||||||
