Angiotensin II receptor type 2, also known as the AT2 receptor is a protein that in humans is encoded by the AGTR2 gene.[5]
Function
Stimulation of AT2 by the selective agonist CGP 42112A increases mucosal nitric oxide production.[7]
Gene
Angiotensin II receptor type 2 (AGTR2) gene is a protein coding gene responsible for encoding AGTR2, the integral membrane protein that binds to two different G-protein coupled receptors. AGTR2 has recently been discovered to play a role in modifying lung disease. This receptor functions to mediate signaling in lung fibrosis and regulate nitric oxide synthase expression in pulmonary endothelium. [8] AGTR2 has recently been prescribed as a target for lung inflammation therapy in cases of cystic fibrosis (CF). The X-chromosome region associated with CF lung disease is located in a non-coding region 3′ of the AGTR2 gene. The modification effect is likely due to variation in gene regulation rather than a change in protein coding sequence.
Variants at the X-chromosome locus containing AGTR2 gene were identified as significantly associating with lung function in patients with cystic fibrosis. Genetically modified mouse studies determined that absence of the AGTR2 gene normalized pulmonary function indicators in two independent CF mouse models. Furthermore, pharmacological antagonism of AGTR2 signaling improved lung function in CF mice to near wild-type levels. Manipulation of the angiotensin-signaling pathway to reduce AGTR2 signaling may be translatable for the treatment or prevention of CF.[9]
