Phosphorylation

Phosphorylation is a type of post-translational modification in which one of the phosphate groups found in molecules like ATP (adenosine triphosphate) is added to the amino acid side chain of a protein or other molecule. By this process, proteins can be activated or deactivated, thus controlling their activity and function. Phosphorylation is a highly important reaction in cell biology, as it is involved in many key cellular processes such as metabolic pathways, signal transduction, gene expression and protein-protein interactions. Due to its widespread use, phosphorylation has become a popular therapeutic target for many diseases including cancer and diabetes. As a result, scientists are exploring ways to modulate or manipulate the phosphorylation process to develop therapies for a range of medical conditions.
