Phosphatases are enzymes responsible for removing phosphate groups from proteins. If phosphatases were nonfunctional, the signaling cascade would continue even in the absence of ligand because the corresponding protein would remain phosphorylated and active, leading to continuous signal transduction. This could potentially result in overstimulation of the pathway and affect cell function.
