Introduction Click to copy section linkSection link copied! Cell signaling is vital for cells to coordinate activities and respond rapidly to changes in their environment. Reversible post-translational modifications (PTMs) are one mechanism by which cells implement such communication networks. (1) Among the most studied PTMs is phosphorylation, which can act as a molecular switch, for example, activating or deactivating proteins via the activities of kinases and phosphatases.
