PI 3-kinase and disease
Phosphoinositide 3-Kinase (PI3K) is a central enzyme in a signaling pathway that mediates cellular responses to insulin and other growth factors. This enzyme phosphorylates the 3 position of phosphatidylinositol-4,5-bisphosphate to produce phosphatidyl-inositol-3,4,5-trisphosphate (PIP3) at the plasma membrane. A number of signaling proteins, including the Ser/Thr protein kinases, AKT and PDK1,...
متن کاملPI 3-kinase
When I was an undergraduate at Caltech, I worked in Bob Edgar’s laboratory on an obscure aspect of phage T4 morphogenesis, which had previously been studied by a little-known South African geneticist, Sydney Brenner [1]. I remember a journal club presented by one of the graduate students in the lab, about the lac repressor binding to DNA. I don’t remember the precise experiments but I know I wa...
متن کاملPI 3-kinase inhibition: a therapeutic target for respiratory disease.
Asthma and COPD (chronic obstructive pulmonary disease) are a growing major health burden, which, despite improvements in disease management, still require new effective treatments. As our understanding of the cellular and molecular processes which govern respiratory diseases improves, the range of potential therapeutic targets increase. PI 3-kinases (phosphoinositide 3-kinases) are a family of...
متن کاملThe phosphoinositide (PI) 3-kinase family.
Phosphoinositide (PI) 3-kinase was first observed in 1984 as a minor inositol lipid kinase activity associated with immunoprecipitated oncogene products (e.g. Src, Abl and polyoma mT antigen) and present in activated growth factor receptor complexes (e.g. PDGF receptor). In 1988, the enzyme associated with this activity was found to have the novel ability to phosphorylate the 3 position hydroxy...
متن کاملPotential sites of PI-3 kinase function in the endocytic pathway revealed by the PI-3 kinase inhibitor, wortmannin
Previously we have shown that PDGF receptor mutants that do not bind PI-3 kinase internalize after ligand binding, but fail to downregulate and degrade. To define further the role of PI-3 kinase in trafficking processes in mammalian cells, we have investigated the effects of a potent inhibitor of PI-3 kinase activity, wortmannin. At nanomolar concentrations, wortmannin inhibited both the transf...
