Sodium potassium pump

Textbook-style schematic of the sodium-potassium pump as a large asymmetrical transmembrane carrier protein embedded in a lipid bilayer. The protein has a bulky two-lobed body with several folded transmembrane helical segments, a central transport core with distinct ion-binding pockets for sodium and potassium, and clear extracellular and intracellular openings suggesting alternating open conformations and directional active transport. Include a cytoplasmic ATP-binding lobe/domain. The pump is rendered as a stylized biological protein icon in blue-purple, teal-green, or blue-green tones, with a broad membrane-spanning shape and clearly differentiated transport features consistent with export of three sodium ions and import of two potassium ions.
