WebThe sodium pump ( Na+/K+-ATPase) is responsible for two thirds of the basal energy expenditure of the brain. It works constantly in the background to maintain the intracellular and extracellular sodium and potassium ion concentrations and is therefore essential for electrical activity in nerve cells (see Ch. 6).
WebATP1A3 encodes the α3 subunit of the sodium-potassium ATPase, one of two isoforms responsible for powering electrochemical gradients in neurons. Heterozygous pathogenic ATP1A3 variants produce several distinct neurological syndromes, yet the molecular basis for phenotypic variability is unclear. We … 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.
