Rpd3 mutants are not defective for interaction with Sin3. Extracts from rpd3 deletion strains expressing Sin3 (S) (lane 1) or HA-tagged Sin3 (SH) (lan es 2–6) and the indicated Rpd3 derivatives were immunoprecipitated with antibodies to the HA-1 epitope (lanes 7–12). Immunoprecipitates were washed with 500 mm of potassium acetate, 1% NP-40, and the resulting samples were immunoblotted and probed with antibodies to Rpd3.
