What is the function of phosphatases?

Phosphatases are enzymes that remove phosphate groups from proteins, lipids, and other molecules, playing a crucial role in cellular signaling and regulation. By dephosphorylating substrates, they can modify protein activity, influence metabolic pathways, and regulate cell division and growth. This action counterbalances the activity of kinases, which add phosphate groups, thus maintaining a delicate balance in various biological processes. Overall, phosphatases are essential for controlling numerous physiological functions and maintaining cellular homeostasis.
