transphosphorylation

Example:The phosphorylation of certain tumor suppressor proteins can inhibit their growth-suppressing function, leading to cell proliferation.

Definition:The addition of a phosphate group to a molecule, often a protein, which can change its activity.

Example:Regulation of kinase activity, including transphosphorylation, is critical for the control of cell growth and differentiation.

Definition:The enzymatic activity of kinases, which catalyze the transfer of a phosphate group from ATP to a substrate molecule.
