Cofilin stress fiber
WebInhibiting formin protein expression results in a decreased filament elongation rate (0.1 µm/min), coupled with abnormal stress fiber morphology and an accumulation of actin binding proteins (e.g. α-actinin). Ena/VASP proteins support formin-mediated filament elongation by tethering the filaments near sites of active actin assembly .
