| Scientific Background: | Angiotensin II receptor type 2 or AT2 is one of the receptors that binds the octapeptide hormone Angiotensin II (Ang II). Most of the physiological actions of Ang II are mediated by AT1 a member of the 7-transmembrane domain, G protein-coupled receptor (GPCR) superfamily. AT2 is also a GPCR, and is largely believed to have counter-regulatory roles to the ones exerted through the AT1 receptor. Hence, binding of Ang II to the AT2 receptor will result in growth arrest and apoptosis, vasodilatation and hypotension. Although the AT2 receptor is structurally a member of the GPCR superfamily, the signaling mechanisms elicited following AT2 receptor activation are not fully clarified. Research indicates that the AT2 receptor signals through the Gia2 and the Gia3 proteins and through the activation of phosphotyrosine phosphatases such as SHP-1. The AT2 receptor distribution is more restricted than that of the AT1 receptor. The highest expression levels of AT2 have been found in the fetus, which is followed by a marked decrease shortly after birth. Nevertheless, significant AT2 receptor expression can be detected in the heart, kidney, vascular endothelial cells and brain. |
