| Mechanism |
Hypertensive effects Induction of sodium and fluid retention |
Antihypertensive agent Alpha-1 adrenergic receptor Antagonist |
|||||||
| Key Mechanism Factor 1 | |||||||||
| Factor Name | Adrenergic receptor alpha-1 | Structure Sequence | |||||||
| Protein Family | G-protein coupled receptor 1 family | ||||||||
| Protein Function |
This alpha-adrenergic receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. Its effect is mediated by G(q) and G(11) proteins. Nuclear ADRA1A-ADRA1B heterooligomers regulate phenylephrine(PE)-stimulated ERK signaling in cardiac myocytes.
