  • Title: [Role of tropomyosin in the sensitivity of (Na+ + K+) ATPase to ouabain].
    Author: Charlemagne D, Léger J, Schwartz K, Geny B, Zachowski A, Lelièvre L.
    Journal: C R Seances Acad Sci D; 1979 Mar 19; 288(11):963-6. PubMed ID: 223773.
    Abstract:
    EDTA treatment of isolated plasma membranes from MF2S cells increased 1,000 fold the sensitivity of (Na+ + K+) ATPase activity to ouabain. The original sensitivity of the enzyme to the drug is recovered after addition of tropomyosin together with Ca++ ions to the treated membranes.
