Figure 9. Role of ATPase function and putative CUE-motif in Fun30 activity.

Figure 9

A. Silencing of the ADE2 reporter in YLS586; fun30Δ is restored by expressing wildtype Fun30 in trans, but not by a Fun30 ATPase mutant or by a control vector expressing LacZ. Expression of Fun30 with the putative CUE motif deleted does not restore silencing as monitored by red pigment formation. Expression was in galactose at 30°C, driven by the galactose-inducible promoter of GAL1. B. Immunoblot analysis of the Fun30 protein in trans-expression with anti-V5 antibody. An immunoblot for histone H3 served as protein loading control. V5-tagged Fun30 and indicated mutants thereof were expressed in trans in a galactose- or glucose dependent manner in Fun30 containing strain JRY7385 from multicopy plasmids, the control vector expresses V5-tagged beta-galactosidase. C. Cells from (B) were serially diluted 10-fold, spotted on media with galactose or with glucose and grown for 3 days at 30°C.
