Angiotensin II receptor type 1 - Wikipedia
Angiotensin II receptor type 1 (AT1) is a G q/11 -coupled G protein-coupled receptor (GPCR) and the best characterized angiotensin receptor. It is encoded in humans by the AGTR1 gene. AT1 has vasopressor effects and regulates aldosterone secretion. It is an important effector controlling blood pressure and volume in the cardiovascular system.
Understanding Angiotensin II Type 1 Receptor Signaling in …
2018年3月26日 · The losartan-sensitive receptor was termed AT 1 (angiotensin II receptor type 1) receptor. It was assumed to be a heterotrimeric GPCR (G protein–coupled receptor) because it generates inositol triphosphate and diacylglycerol, leading to intracellular Ca 2+ elevation and protein kinase C activation, respectively.
Angiotensin II receptor - Wikipedia
The angiotensin II receptors, (ATR1) and (ATR2), are a class of G protein-coupled receptors with angiotensin II as their ligands. [1] They are important in the renin–angiotensin system: they are responsible for the signal transduction of the vasoconstricting stimulus of the main effector hormone, angiotensin II. [2]

The RAS consists of the Ang II precursor angiotensinogen; renin; angiotensin-converting enzyme (ACE); Ang II; and Ang II type 1 and type 2 receptors (AT1R and AT2R). Ang II is the main effector molecule of the RAS, deriving from angiotensinogen by …
Angiotensin II Type I Receptor (AT1R): The Gate towards COVID …
AT1R, a member of the G protein-coupled receptor (GPCR) family, modulates Ang II deleterious effects through the activation of multiple downstream signaling pathways, among which are MAP kinases (ERK 1/2, JNK, p38MAPK), receptor tyrosine kinases (PDGF, EGFR, insulin receptor), and nonreceptor tyrosine kinases (Src, JAK/STAT, focal adhesion ...
Angiotensin II Receptor Type 1 - an overview - ScienceDirect
The angiotensin II type 1 receptor (AT1R) was one of the earliest GPCRs for which evidence of biased signaling was shown. Angiotensin II (AngII) regulates cardiovascular functions and increased levels have been linked to hypertension, renal dysfunction and heart failure.
AT1 receptor signaling pathways in the cardiovascular system
The angiotensin II type 1 receptor (AT1 receptor) is one of the key players in the renin angiotensin aldosterone system. The AT1 receptor promotes various intracellular signaling pathways resulting in hypertension, endothelial dysfunction, vascular remodeling and end organ damage.
