title: Angiotensin receptor mediated regulation of transport in the rat proximal tubule.
abstract: The intracellular mechanism of Ang II action, as supported by the present data, may be summarized by the following: Ang II interacts with its receptors, leading to an increase in cytosolic Ca+2 by mobilization of Ca+2 from intracellular pools. This rise in cytosolic Ca+2 initiates the activation of calmodulin-regulated enzymes. This then leads to inhibition of both JV and JHCO3-.
