The interaction between GLT-1 and Hsp90β. (A) Illustration of GLT-1 truncations. The region between two red lines is indispensable for GLT-1 and Hsp90β interaction (B and C) Representative Western blot analysis for Hsp90β-FLAG after immunoprecipitation of full-length GLT-1-myc and truncations (n = 3). 293t cells were transfected with full-length GLT-1 or truncated GLT-1 (a–e). Asterisk indicates IgG heavy chain. (D) Structural features of the mammalian GLT-1 in lipid bilayer. All data are representative of at least three independent experiments. TM, transmembrane; HP1, 2, hairpin (HP) loops 1, 2. All experimental data were verified in two independent experiments.
