      DescriptionWortmannin, (PI3 Kinase inhibitor)
      OverviewWortmannin, a fungal metabolite, is a cell-permeable, irreversible inhibitor of phosphatidylinositol 3 kinase (PI3 Kinase) with an IC50 of 5nM. It blocks the catalytic activity of PI3-Kinase without affecting upstream signaling events such as insulin receptor tyrosine kinase activity. Wortmannin also inhibits the activities of myosin light chain kinase and PI4-Kinase at concentrations a hundred times higher than those required to inhibit PI3-Kinase.
      Product Information
      Presentation1mg of lyophilized powder packaged under inert gas. White to off-white powder.
      ApplicationThe Wortmannin, (PI3 Kinase inhibitor) controls the biological activity of PI3 Kinase. This small molecule/inhibitor is primarily used for Biochemicals applications.
      Key Applications
      • Kinase Assay
      Biological Information
      Entrez Gene Number
      Entrez Gene SummaryReceptor-regulated class I phosphoinositide 3-kinases (PI3Ks) phosphorylate the membrane lipid phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) to PtdIns(3,4,5)P3, which in turn recruits and activates cytosolic effectors involved in proliferation, survival, or chemotaxis. PIK3R5 is a PI3K regulatory subunit (Brock et al., 2003 [PubMed 12507995]).[supplied by OMIM]
