essential for life in eukaryotic cells. The combinatorial action of both protein tyrosine kinases
and protein tyrosine phosphatases (PTPs) determines the net level of cellular tyrosine
phosphorylation. This unit discusses methods to determine the level of protein tyrosine
phosphatase activity and methods for discovering novel substrates for protein tyrosine
phosphatases. Curr. Protoc. Mol. Biol. 91: 18.16. 1‐18.16. 17.© 2010 by John Wiley & Sons …
