ATP1A3


ATP1A3

A gene on chromosome 19q13.31 that encodes an enzyme belonging to the family of P-type cation transport ATPases and the subfamily of Na+/K+ -ATPases, the latter of which are responsible for establishing and maintaining electrochemical gradients of Na and K ions across the plasma membrane; they are required for osmoregulation in sodium-coupled transport of various organic and inorganic molecules, and for electrical excitability of nerve and muscle.
