Abstract
The Na+/K+-ATPase (also known as the “sodium–potassium pump” or just “sodium pump”) is a ubiquitous and critically important protein complex in the human body. In the brain, between 40 and 70% of all energy is spent maintaining its ionic transport activity [1,2,3]. This energy is used for the active exchange of cytosolic sodium for extracellular potassium in a 3:2 ratio, a process required for the maintenance of transmembrane ionic gradients for all mammalian cells, which in turn is essential for setting the cellular resting potential, regulating osmolarity, and powering the secondary transport of other important solutes like calcium (via the sodium–calcium exchanger) and protons (via the sodium–hydrogen exchanger)
