Application

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

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.

Cell signaling, one of key processes in both normal cellular function and disease, is coordinated by numerous interactions between membrane proteins that change in response to stimuli. We present a split ubiquitin-based method for detection of integral membrane protein-protein interactions

c-Met signaling has been implicated in oncogenesis especially in cells with c-met gene amplification. Since 20 % of gastric cancer patients show high level of c-Met expression, c-Met has been identified as a good candidate for targeted therapy in gastric cancer.

A 78-amino acid insertion (L78) is found in the low-affinity type (L-form) of starch phosphorylase (L-SP, EC 2.4.1.1). This insertion blocks the starch-binding site on the L-SP molecule, and it decreases the binding affinity of L-SP toward starch. The computational
