  • Title: Enhancement of the transfer of alpha-tocopherol between liposomes and mitochondria by rat-liver protein(s).
    Author: Mowri H, Nakagawa Y, Inoue K, Nojima S.
    Journal: Eur J Biochem; 1981 Jul; 117(3):537-42. PubMed ID: 7285904.
    Abstract:
    alpha-Tocopherol transfer from liposomes to mitochondria was enhanced by a cytosolic protein in rat liver. This protein was separated from the exchange protein specific for phosphatidylcholine. The stimulation was specific for alpha-tocopherol and the "affinity" order of tocopherols for the cytosolic protein was found to be as follows: alpha-tocopherol greater than gamma-tocopherol much greater than alpha-tocopheryl acetate, alpha-tocopherol quinone. The transfer-stimulating protein may act as a carrier, since an intermediate (alpha-tocopherol)-protein complex could be detected when liposomes containing alpha-tocopherol were incubated with the cytosol. This transfer-stimulating activity was present not only in liver, but also in heart, spleen and lung.
