    ..Our data reveal a different mode of APC regulation by Rca1 at the G2 stage, when low Cdk activity is unable to inhibit Cdh1(Fzr) interaction. ..

    ..Our results reveal a novel protein kinase complex that controls S phase at the onset of development apparently by stabilizing mitotic cyclins. ..

    ..A 13 kb wild-type genomic DNA containing the Cyclin-A transcription units rescued the mutant phenotype when introduced into the mutant fly. The regulation of cell type specific expression of the Cyclin-A gene is discussed. ..
