| 产品介绍 | The Angiotensin II type 1 receptor (AT1) is the primary effector of Angiotensin II, a key regulator of blood pressure and fluid homeostasis. It is involved in pathogenesis of several cardiovascular diseases such as hypertension, cardiac hypertrophy and congestive heart failure. Angiotensin II interacts with two types of G-protein coupled membrane receptors, AT1 (type 1) and AT2 (type 2). AT1 has three isoforms in rodents: AT1A (359 aa), AT1B (359 aa), and AT1C (177 aa). Rat AT1's are predicted to contain seven transmembrane domains. The N-terminus is predicted to be extracellular, while the C-terminus is predicted to be cytoplasmic. AT1's are expressed in the liver, kidney, aorta, lung, uterus, ovary, spleen, heart, adrenal and vascular smooth muscle. Function: Receptor for angiotensin II. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. Subunit: Interacts with MAS1 (Probable). Interacts with ARRB1. Subcellular Location: Cell membrane; Multi-pass membrane protein. Tissue Specificity: Liver, lung, adrenal and adrenocortical adenomas. Post-translational modifications: C-terminal Ser or Thr residues may be phosphorylated. DISEASE: Renal tubular dysgenesis (RTD) [MIM:267430]: 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). Note=The disease is caused by mutations affecting the gene represented in this entry. Similarity: Belongs to the G-protein coupled receptor 1 family.

底物,即血管紧张素原,在肾素的作用下水解,产生一个十肽,为血管紧张素I。在血浆和组织中,特别是在肺循环血管内皮表面,存在有血管紧张素转换酶,在后者的作用下,血管紧张素I水解,产生一个八肽,为血管紧张素Ⅱ。血管紧张素Ⅱ在血浆和组织中的血管紧张素酶A的作用下,再失去一个氨基酸,成为七肽血管紧张素Ⅲ。上述过程可由图4-28表示。血管紧张素Ⅱ和血管紧张素Ⅲ作用于血管平滑肌和肾上腺皮质等细胞的血管紧张素受体,引起相应的生理效应。 当各种原因引起肾血流灌注减少时,肾素分泌就会
