DUE-B interacts with the MCM complex. A, DUE-BSf9 was incubated with interphase egg extract and fractionated by gel filtration. Mcm7 and DUE-B were detected using specific antibodies. B, interphase egg extract was treated with RNase A and then incubated with DUE-BSf9. C, DUE-BSf9 was incubated with benzonase nuclease-treated interphase egg extract and then immunoprecipitated (IP) by affinity purified DUE-B antibody or normal rabbit IgG. The immunoprecipitates were resolved by SDS-PAGE and probed for specific proteins. D, DUE-BSf9 was incubated with benzonase nuclease-treated interphase egg extract. Mcm3 or Mcm5 were immunoprecipitated by specific antibodies. The immunoprecipitates were resolved by SDS-PAGE and Western blotted for DUE-B.
