Figure 5. Depletion of Coronin 1B alters lamellipodial dynamics and inhibits SSH1L-induced membrane ruffling.
A- Depletion of Coronin 1B inhibits SSH1L-induced hyper-ruffling. Rat2 fibroblasts stably expressing SSH1L or FP4-CAAX were transfected with the Coronin 1B shRNA, and the cells were subjected to kymography analysis as described in Fig. 1E. Newman-Keuls multiple comparison test was used after one-way ANOVA to generate the P values.
B- Cofilin S3D suppresses SSH1L-induced hyper-ruffling. Phospho-mimetic mutants of either Coronin 1B (S2D) or Cofilin (S3D) were transiently expressed in Rat2 fibroblasts stably expressing SSH1L-GFP; kymography analysis was carried out as in Fig. 1E.
