P-type ATPases are essential molecular pumps that transport a wide range of substrates across biological membranes using ATP as an energy source. These transporters are fundamental to numerous cellular processes, including:

• Establishing vital ion gradients

• Regulating uptake and extrusion of heavy metals and polyamines

• Maintaining lipid asymmetry and driving vesicle formation

Through these functions, P-type ATPases enable communication between the extracellular and intracellular environments and act as critical regulators of cellular and organelle physiology.

​

Despite sharing a common structural architecture and catalytic mechanism, each P-type ATPase is unique in its substrate specificity, regulatory mode, subcellular localization, and tissue distribution. Dysregulation or dysfunction of these proteins e.g. by mutations in their encoding genes, are linked to several human diseases. Consequently, P-type ATPases represent promising therapeutic targets for drug discovery and development.
