Tic110 also contains a docking site for preproteins at the stromal side of the inner membrane (15). At least one cochaperone, the integral inner membrane protein, Tic40, participates in import by facilitating the interaction of Hsp93, Tic110, and preproteins during the import reaction (9, 16, 17).

Webb18 feb. 2024 · The Tic110 complex migrates at ~230 kDa on BN-PAGE, but the stoichiometry of this complex has not been determined [10, 11]. Tic110, which does not associate with the 1-MDa complex, has been proposed to function as a scaffold for stromal chaperones [12-14]. Tic110 has also been proposed to function as the pore itself . WebbTranslocation of nuclear-encoded preproteins across the inner envelope of chloroplasts is catalyzed by the Tictranslocon, consisting of Tic110, Tic40, Tic62, Tic55, Tic32, Tic20, and Tic22. Tic62 was proposed to act as a redox sensor of the complex because of its redox-dependent shuttling between envelope and stroma and its specific interaction with the …
