The sodium–potassium pump (Na⁺/K⁺-ATPase) is an important membrane protein that plays a key role in membrane biology and bioenergetics by maintaining ionic balance and generating electrochemical gradients across the plasma membrane. It is present in the membranes of most animal cells and actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients using energy derived from ATP hydrolysis.
