WebThe pump simply maintains the concentrations gradients over a long time period. But: When an action potential occurs, only a tiny, tiny amount of ions (<0.001%) need to move across the membrane to change the membrane … The sodium–potassium pump (sodium–potassium adenosine triphosphatase, also known as Na⁺/K⁺-ATPase, Na⁺/K⁺ pump, or sodium–potassium ATPase) is an enzyme (an electrogenic transmembrane ATPase) found in the membrane of all animal cells. It performs several functions in cell physiology. The Na⁺/K⁺ … See more The Na⁺/K⁺-ATPase helps maintain resting potential, affects transport, and regulates cellular volume. It also functions as a signal transducer/integrator to regulate the MAPK pathway, reactive oxygen species (ROS), as well as … See more Endogenous The Na⁺/K⁺-ATPase is upregulated by cAMP. Thus, substances causing an increase in cAMP … See more • Alpha: ATP1A1ATP1A1, ATP1A2ATP1A2, ATP1A3ATP1A3, ATP1A4ATP1A4. #1 predominates in kidney. #2 is also known as "alpha(+)" See more • Thyroid hormone • V-ATPase See more Looking at the process starting from the interior of the cell: • The pump has a higher affinity for Na⁺ ions than K⁺ ions, … See more Na⁺/K⁺-ATPase was discovered by Jens Christian Skou in 1957 while working as assistant professor at the Department of Physiology, University of Aarhus, Denmark. He published his … See more Mutagenesis studies conducted by Susanne Dobler have identified the conserved M3-M4 hairpin and M5-M6 hairpins.
