  • Title: Transfer of insulin receptors and of glucose transport-inducing proteins onto phospholipid vesicles.
    Author: Solomon B, Incerpi S, Miller IR.
    Journal: Biochim Biophys Acta; 1980 Aug 14; 600(3):931-8. PubMed ID: 7190841.
    Abstract:
    Insulin receptors and glucose transport-inducing proteins have been extracted from rat liver membranes onto positively charged lipid bilayer vesicles. The extraction was carried out during the incubation of the vesicles with lipid vesicles caused an overall enhancement of specific insulin binding and of glucose transport inducement. The latter has been inferred from the oxidation rate of transported glucose through a spherical bilayer membrane entrapping the oxidizing glucose oxidase. Glucose transport is not enhanced by insulin binding, indicating that the two functions baecome dissociated when the proteins are transferred from the plasma membrane onto the bilayer vesicles.
