Activity summary

The Angiotensin II Type 1 Receptor also known as AGTR1 AT1 receptor or Angiotensin Receptor 1 is a G protein-coupled receptor with a mass of approximately 45 kDa. This receptor binds to the angiotensin II peptide playing a central role in regulating blood pressure. It is broadly expressed in tissues such as vascular smooth muscle cells cardiac myocytes kidneys and brain. The AT1 receptor mediates vasoconstriction aldosterone secretion and cellular growth through its interaction with angiotensin II impacting cardiovascular functions.

Biological function summary

The Angiotensin II Type 1 Receptor contributes significantly to the regulation of cardiovascular homeostasis. It forms part of a complex signaling system involving G proteins phospholipase C and other downstream effectors. This receptor elicits responses important for maintaining vascular tone and fluid balance. By activating intracellular signaling cascade it plays an essential role in sodium reabsorption and systemic blood pressure maintenance. The receptor's expression and activity represent an important component in cardiovascular function.

Pathways

The AT1 receptor participates actively in the renin-angiotensin system (RAS) and is a significant player in the regulation of blood pressure. It interacts with angiotensin converting enzyme (ACE) and angiotensin II within this pathway. Additionally the receptor is linked to the mitogen-activated protein kinase (MAPK) pathway which further influences cell proliferation and vascular remodeling. These interactions highlight the receptor's involvement in vascular smooth muscle cell function and the broader implications for cardiovascular health.

Associated diseases and disorders

The Angiotensin II Type 1 Receptor is closely associated with conditions such as hypertension and heart failure. Dysfunction or overactivity of this receptor contributes to elevated blood pressure and compromised cardiac function. The AT1 receptor's connection to ACE highlights its therapeutic relevance as many antihypertensive treatments target this interaction. By modulating the receptor's activity these treatments aim to alleviate symptoms and reduce the risk of cardiovascular events.
