Figure 11. CDK activity antagonizes Whi5-HDAC interactions.

Figure 11

(A) Pho85 and Cdc28 activity inhibits interaction between Whi5 and Rpd3. PCL9FLAG (pBA1974), CLN2FLAG (pBA2247), CLN3FLAG (pBA2248), or a vector control (pMT3164) were introduced into a strain harboring RPD3TAP at the chromosomal locus (BY4315) and a WHI5GST plasmid (pBA1973). Cyclin expression was confirmed by immunoblot using anti-FLAG antibodies. Lysates were incubated with glutathione sepharose beads. Whi5GST-Rpd3TAP interactions were detected by immunoblot using α-GST and α-PAP antibodies, (B) Pho85 and Cdc28 activity inhibits interaction of Whi5 and Hos3. Experiments were conducted as described in (A) but using a strain bearing HOS3TAP at the chromosomal locus.
