WebWhen studying cellular processes involving protein phosphorylation such as signaling cascades and protein-protein interactions, or analysis of phosphorylated sites on a protein and phosphoprotein purification, it is essential to inhibit cellular protein phosphatases by phosphatase inhibitors. WebProtein tyrosine phosphatases (PTP) represent a large family of enzymes that play a very important role in intra- and intercellular signaling. PTPs work antagonistically with protein tyrosine kinases to regulate signal transduction pathways in response to a variety of signals, including hormones and mitogens.
