angiotensin II signaling pathway angiotensin II signaling pathway via AT2 receptor Angiotensin II signaling through the angiotensin type 2 receptor (AT2) is less well understood and rather controversial. It appears to counteract AT1 receptor function and promote apoptosis. Alternatively, it may complement the effects of AT1 receptor with deleterious consequences in cardiac pathologies. AT2 receptor appears to function in a G-protein dependent as well as independent manner. PW:0000528 pathway
