Phosphorylation
Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule. Phosphorylation and its counterpart, dephosphorylation, turn many protein enzymes on and off, thereby altering their function and activity. Protein phosphorylation is one type of post-translational modification.Protein phosphorylation in particular plays a significant role in a wide range of cellular processes. Its prominent role in biochemistry is the subject of a very large body of research (as of March 2015, the Medline database returns over 240,000 articles on the subject, largely on protein phosphorylation).
