Protein Phosphorylation

Protein phosphorylation is a chemical process where a phosphate group is added to a protein, often altering its function. This modification can change how a protein interacts with other molecules, influences its activity, or affects its location within a cell. Phosphorylation plays a crucial role in various cellular processes, including signaling pathways that regulate growth, metabolism, and response to external signals. It is a key mechanism cells use to control and coordinate biological functions, making it essential for maintaining health and responding to changes in the environment.
