BSA結合ホスホチロシン

アプリケーション

Monoclonal Anti-Phosphotyrosine-Agarose antibody produced in mouse has been used in:

• immunoprecipitation experiments for affinity-purification of phosphotyrosine proteins
• phosphotyrosine pulldown assays
• PI3-kinase assay

Proteins containing phosphotyrosines were deteced in protein extracts from dissected tissue of Harlan Sprague Dawley rats or from transfected HEK293 cells using mouse monoclonal anti-phosphotyrosine antibody as the primary antibody. Reactivity was blocked when extracts were previously treated with 10 mM phosphotyrosine but not 10 mM tyrosine showing the specifity of the antibody for phosphorylated tyrosines. Immunoprecipitation of proteins containing phosphorylated tyrosines in rat dorsat root ganglion homogenates was performed using mouse monoclonal anti-phosphotyrosine. The antibody was incubated with the homogenates in the presence of 50 mm NaF and protease inhibitors for 4-14 hours at 4°. The antibody was precipitated using Protein G-agarose beads incubated overnight.

生物化学的／生理学的作用

Reversible phosphorylation of proteins is an important post-translational modification that plays a regulatory role in the expression of most proteins in the cells. Reversible phosphorylation at multiple serine, tyrosine and threonine residues mediate numerous signalling pathways in both prokaryotic and Eukaryotic cells. Cellular proteins with phosphorylated tyrosine increase many fold by the activation of tyrosine kinases. Most mitogenic receptor systems such as EGF, PDGF, insulin receptors contain tyrosine kinase domains that undergo autophosphorylation when receptors bind to the respective ligands. Tyrosine-specific protein kinase activity has also been described in many retroviral oncogene proteins. Cells transformed by these oncogenes contain elevated levels of phosphotyrosine. Many of the oncogenes found in mammalian oncogenic viruses encode tyrosine protein kinases that reside in the cellular cytoplasm. Others encode transmembrane receptors whose tyrosine phosphotransferase activity is stimulated by the binding of ligand to the extracellular domain.
