Application

O-Phospho-L-tyrosine has been used:
  • as a diluent of anti-phosphotyrosine antibody to study sperm capacitation[1]
  • as an amino acid standard in liquid chromatography with tandem mass spectrometry (LC-MS-MS) analysis[2]
  • as an amino acid standard in two-dimensional thin-layer electrophoresis system to analyze phosphoamino acids on the phosphorylated starch phosphorylase (L-SP)[3]

Biochem/physiol Actions

Phosphotyrosine acts as a docking site in protein regulation by stimulating interaction between tyrosine-phosphorylated proteins and phosphotyrosine domains of other proteins.[4]
