Hormonal Modulation of Sodium Pump Activity: Identification of Second Messengers,ysis of ATP. Electrochemical gradients of sodium and potassium are formed that initiate the subsequent diffusion of sodium and potassium, which helps establish the resting membrane potential. Under normal physiologic conditions three Na. ions are expelled in exchange for two K. ions, which produces

This diversity results from the expression of different or related genes, from the alternative splicing of a primary transcript, or from posttranslational modifications. In addition, the assembling of different channel proteins into heteromultimeric speci

Moreover, venous plasma potassium is not a very accurate indicator of body potassium homeostasis. Accordingly, in

The Clinical Pharmacology of Potassium Channels,pharmacologic properties, are known than of any other type of ion channel. One of the most important roles of these channels is the regulation of membrane potential and excitability in nerve and muscle cells. Many potassium channels in turn are regulated by second messengers and other molecules of i
