摘要: Cell division in higher eukaryotes is mainly controlled by CDK (serine/threonine) protein kinases and other components of these kinase complexes. Previously, we showed homologous also occur the ciliate Paramecium tetraurelia. In this report, a polyclonal antibody was produced against GST fusion which contained N-terminal third previously isolated CDC2PTA protein. It recognized 36 kDa polypeptide on western blots did not cross-react with related 34 polypeptide. This no affinity for yeast P13 suc1 The level invariant throughout cell cycle decreased slightly when cells entered stationary phase. Indirect immunofluorescence localized macronucleus, but micronuclei. Native immunoprecipitated activity assayed using histone H1 as substrate elutriation synchronized samples. high during early stages reached peak at 2.5 h after elutriation, corresponds to time initiation macronuclear DNA synthesis. suggests may be associated regulation These results allow us draw concrete comparisons first between role ciliates eukaryotes.
