Protein Phosphorylation Inhibition

**Semantic type:** Molecular Function

**Definition:** Protein Phosphorylation Inhibition involves interference with, or restraint of, enzymatic activities involved in covalent transfer of a phosphate group from ATP to a protein via the action of a kinase. The major phosphoryl acceptors in proteins are serine, threonine, and tyrosine. Typically, such post-translational modifications regulate protein function.
