General description

A broad spectrum potent inhibitor of protein tyrosine phosphatases. Also known to inhibit Na+,K+-ATPase, acid and alkaline phosphatases, phosphofructokinase, and adenylate kinase. Also inhibits the ATPase activity of the reconstituted binding protein-dependent ATP-Binding Cassette (ABC) transporter for maltose (MalFGK2) of Salmonella typhimurium in the micromolar range. Can be converted to pervanadate by hydrogen peroxide.
A broad spectrum potent inhibitor of protein tyrosine phosphatases. Also known to inhibit Na+/K+ ATPase, acid and alkaline phosphatases, phosphofructokinase, and adenylate kinase. Most recently shown to inhibit ATPase activity of the reconstituted binding protein-dependent ATP-Binding Cassette (ABC) transporter for maltose (MalFGK2) of Salmonella typhimurium in the micromolar range. Can be converted to pervanadate by hydrogen peroxide.

Endocytosis of ligand-activated receptors requires dynamin-mediated GTP hydrolysis, which is regulated by dynamin self-assembly. Here, we demonstrate that phosphorylation of dynamin I by c-Src induces its self-assembly and increases its GTPase activity. Electron microscopic analyses reveal that tyrosine-phosphorylated dynamin I
