The Phosphorylation Code

The phosphorylation code refers to how cells use the addition of phosphate groups (phosphorylation) to specific proteins to control their activity, interactions, and location within the cell. This process acts like a molecular switch, turning proteins on or off or changing how they behave. Different patterns of phosphorylation serve as a code that can be read by other proteins, guiding cellular processes such as growth, response to signals, and gene expression. Essentially, it’s a sophisticated system that uses chemical tags to regulate complex biological functions precisely and dynamically.
