Differential effects of nocodazole on newly translated versuss existing NaV1.5.
(A and B) Disrupting microtubules by nocodazole (10 µM, 12 h) prevented newly translated GFP-NaV1.5 from reaching the lateral surface and intercalated discs (A), but did not alter the distribution pattern of native NaV1.5 in ventricular myocytes (B). Scale bars are 10 μm.
