Fig. 3. Cytoplasm viscosity is increased in MyoIB+ and ${Delta}$ SH3 strains. Cytoplasm viscosity was measured in the strains that overproduce the different myosin IB truncated forms. The graphs show the distribution of the values obtained for N phagosome pairs studied in different cells for each strain. The mean value of the cytoplasmic viscosity ( ${eta}$ ) obtained for each strain is indicated±s.d. The ${Delta}$ SH3 strain exhibits an equivalent increase of the cytoplasm viscosity to the MyoIB+ strain. By contrast, the strain overproducing myosin IB deleted for the head domain (Myo-tail+) or the ATP-insensitive actin-binding site TH2 ( ${Delta}$ TH2) display the same viscosity value as the control cells.
