Angiotensin II Type 1 Receptor

Function

Receptor for angiotensin II, a vasoconstricting peptide, which acts as a key regulator of blood pressure and sodium retention by the kidney (PubMed:15611106, PubMed:1567413, PubMed:25913193, PubMed:26420482, PubMed:30639100, PubMed:32079768, PubMed:8987975). The activated receptor in turn couples to G-alpha proteins G(q) (GNAQ, GNA11, GNA14 or GNA15) and thus activates phospholipase C and increases the cytosolic Ca(2+) concentrations, which in turn triggers cellular responses such as stimulation of protein kinase C (PubMed:15611106).

(Microbial infection) During SARS coronavirus-2/SARS-CoV-2 infection, it is able to recognize and internalize the complex formed by secreted ACE2 and SARS-CoV-2 spike protein through DNM2/dynamin 2-dependent endocytosis.

Involvement in disease

Renal tubular dysgenesis

RTD

Autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype).

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

C-terminal Ser or Thr residues may be phosphorylated.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family.

Tissue specificity

Liver, lung, adrenal and adrenocortical adenomas.

Cellular localization

  • Cell membrane
  • Multi-pass membrane protein

Alternative names

AGTR1A, AGTR1B, AT2R1, AT2R1B, AGTR1, Type-1 angiotensin II receptor, AT1AR, AT1BR, Angiotensin II type-1 receptor, AT1 receptor
