Role of Phosphatidylinositol 3-Kinase in Growth Factor and Oncogene Signaling
Phosphatidylinositol 3-kinase (PtdIns 3-Kinase) is an enzyme that phosphorylates the D-3 position of the inositol ring of the membrane lipid, phosphatidylinositol (PtdIns). It was discovered because of its hig...

The colony stimulating factor-1 receptor associates with and activates phosphatidylinositol-3 kinase
COLONY stimulating f actor-1 (CSF-1) is a lineage-specific growth factor required for proliferation and survival of mononuclear phagocytes and their precursors. The CSF-1 receptor belongs to a family of ligan...

Type I phosphatidylinositol kinase makes a novel inositol phospholipid, phosphatidylinositol-3-phosphate
The generation of second messengers from the hydrolysis of phosphatidylinositol-4,5-bisphosphate (PtdInsP2) by phospho-inositidase C has been implicated in the mediation of cellular responses to a variety of grow...

Comparison of the Na+ Pump and the Ouabain-Resistant K+ Transport System with Other Metal Ion Transport ATPases
Digitalis has long been of medical importance and was mentioned in herbal treatment as early as 1250 (Schery, 1972). This drug entered into accepted medical practice in 1785 following the experimental observat...

Association of phosphatidylinositol kinase activity with polyoma middle-T competent for transformation
Polyoma middle-T antigen is required for viral transformation of cultured cells and for tumorigenesis in animals. Like many other transforming gene products, middle-T is bound to the membrane and has an associ...

Na+ and Ca2+ Fluxes and Differentiation of Transformed Cells
Alterations in cation fluxes across the plasma membrane appear to play a central role in the regulation of cellular growth and differentiation [1,2,4,6–8,17,19]. Oocyte maturation is stimulated by Ca2+ release in...

The plasma membrane (Mg2+)-dependent adenosine triphosphatase from the human erythrocyte is not an ion pump
The plasma membrane (Mg2+)-dependent adenosine triphosphatase ((Mg2+)-ATPase) from human erythrocytes has been tested for its ability to transport ions. Using a preparation of inside-out vesicles loaded with the ...
