Cover: Drosophila S2 cells transfected with various human coronin-1B−GFP expression constructs (green) stained with Alexa Fluor-568-coupled phalloidin (red). Overexpression of wild-type coronin 1B induces the formation of F-actin cables, whereas mutants that lack F-actin binding do not induce cables. The cell in the third column, third row was treated with latrunculin B to induce actin depolymerization. Coronin-1B-induced actin cables are resistant to this drug, suggesting that they are protected from depolymerization. See article by L. Cai et al. (pp. 1779-1790).
