Phenyl phosphate disodium salt functions as a phosphatase inhibitor. It acts by inhibiting the activity of phosphatase enzymes, which are responsible for removing phosphate groups from proteins. By blocking the action of phosphatases, Phenyl phosphate disodium salt can be used to study the phosphorylation status of specific proteins and the signaling pathways in which they are involved. Phenyl Phosphate Disodium Salt′s mechanism of action involves binding to the active site of phosphatase enzymes, preventing them from dephosphorylating their protein substrates.
