FIGURE 6:
Sis1 localizes to stress-inducible compartments that contain misfolded proteins and molecular chaperones. (A) Fluorescence microscopy of BY4741 yeast cells expressing Sis1-GFP and mCherry-VHL or GFP-Ubc9ts and Sis1-mCherry. The cells were incubated at 37°C for 1 h in the presence of MG132. (B) BY4741 yeast cells carrying a GFP-tagged chromosomal copy of SIS1 and an mCherry-tagged chromosomal copy of HSP104, HSP42, or SSA1 were observed by fluorescence microscopy after growth at 37°C for 1 h.
