FIGURE 3:
Genetic interactions of roy1, ypt52, and vps21 on cell growth and intracellular trafficking. (A) The indicated yeast cells were grown to exponential phase in YPD medium. Cells were harvested and resuspended in YPD medium to an OD600 of 0.4. Three microliters of 10-fold serial dilutions were spotted onto YPD plates, incubated for 36 h at the indicated temperature, and photographed. (B) The indicated yeast cells were stained with FM2-10 as described in Materials and Methods and analyzed by fluorescence microscopy. Bar, 2 μm. (C and D) The indicated yeast cells were harvested and lysed by the TCA lysis method. Extracts were subjected to IB with the indicated antibodies. (E) The growth of the yeast strains was compared as described in A in the presence of the indicated concentration of monensin at 30°C for 36 h.
