Potassium Channel
KcsA
Potassium channels are the most widely distributed type of ion channel and are found in virtually all living organisms. They form potassium-selective pores that span cell membranes. Potassium channels are found in most cell types and control a wide variety of cell functions. Potassium channels function to conduct potassium ions down their electrochemical gradient, doing so both rapidly and selectively. Biologically, these channels act to set or reset the resting potential in many cells. In excitable cells, such asneurons, the delayed counterflow of potassium ions shapes the action potential. By contributing to the regulation of the action potential duration in cardiac muscle, malfunction of potassium channels may cause life-threatening arrhythmias. Potassium channels may also be involved in maintaining vascular tone.

AU-1421
0 ImagesArt. -Nr.: HY-165569CAS. Nr.: 115717-83-4AU-1421 is a potassium ion (K⁺) site-directed regulator that specifically acts on various cation transport ATPases. AU-1421 can distinguish between two different K⁺-sensitive phosphorylation intermediate (E2P) states: for non-K⁺ transport type ATPases (such as the sarcoplasmic reticulum Ca²⁺-ATPase), after binding to AU-1421, it mimics the agonistic effect of K⁺, significantly accelerating the hydrolysis (dephosphorylation) of E2P. For K⁺ transport type ATPases (such as the gastric mucosa H⁺/K⁺-ATPase and the renal Na⁺/K⁺-ATPase), after binding to AU-1421, it inhibits the hydrolysis of E2P, stabilizing the phosphorylated intermediate, thereby blocking the ion transport cycle. AU-1421 can be used to study the mechanism of the potassium ion pump.
