phosphoprotein phosphatase activity

Molecular Function

Definition (GO:0004721 GONUTS page)

Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cellular proteins and thereby provide an important mechanism for regulating cellular activity.
