    Mol Cell Biol 20:5879-87. 2000
    ..We conclude that the ATPase domain of mtHsp70 is essential for and directly interacts with Tim44, clearly separating the mtHsp70-Tim44 interaction from the mtHsp70-substrate interaction...

    K Dietmeier
    Biochemisches Institut, Universitat Freiburg, Germany
    J Biol Chem 268:25958-64. 1993
    ..Yeast PiC/p32 is thus not only structurally homologous to the ADP/ATP carrier, but has a similar targeting mechanism and submitochondrial location, supporting its classification as a member of the inner membrane carrier family...

    W Voos
    Institut fur Biochemie und Molekularbiologie, Universitat Freiburg, Germany
    EMBO J 15:2668-77. 1996
    ..This is consistent with a model that the dynamic interaction of mtHsp70 with Tim44 generates a pulling force on preproteins which supports unfolding during translocation...

    J Cell Biol 145:961-72. 1999

    W Voos
    Biochemisches Institut, Universitat Freiburg, Germany
    Mol Cell Biol 14:6627-34. 1994
    ..After being imported into the matrix, the preprotein could be coprecipitated only by antibodies against mt-hsp70. We propose that mt-hsp70 and MGE cooperate in membrane translocation of preproteins...
