O-Phospho-L-tyrosine Chemical Properties, Uses, Production
Chemical Properties
White Solid
Uses
O-Phospho-L-tyrosine is used in the study of tyrosine-phosphorylation, which has been linked to the malignant transformation of cells by various RNA tumor viruses. Plays a role in signal transduction.
Definition
ChEBI: A non-proteinogenic L-alpha-amino acid that is L-tyrosine phosphorylated at the phenolic hydroxy group.
Biological Activity
Phosphotyrosine acts as a docking site in protein regulation by stimulating interaction between tyrosine-phosphorylated proteins and phosphotyrosine domains of other proteins.
Purification Methods
Purify it by recrystallisation from H2O or H2O/EtOH. [Levene & Schormüller J Biol Chem 100 583 1933, Posternak & Graff Helv Chim Acta 28 1258 1945, Beilstein 14 III 1510.]
