Figure 6.

Overexpression of mACF7 COOH-terminal domain stabilizes cellular MTs. pFLAG-mACF7-C (A–D) and pFLAG-ABD (E and F) and transfected COS-7 cells were treated with nocodazole (10 μM) for 1.5 h before being fixed and double-labeled with monoclonal anti-FLAG M2 antibody (A, C, and E) polyclonal anti–Tyr-tubulin antibody (B), polyclonal anti–Glu-tubulin antibody (D), and polyclonal antitubulin antibody (F). The overexpressed mACF7-C protein stabilized MTs from depolymerization by nocodazole (compare positive FLAG-staining cell with its neighboring cells in A and B). Bar, 20 μm.
