In this report, we have used bimolecular fluorescence complementation assays in HeLa cells to examine the interactions between Cdc45, Mcm2-7, and the GINS complex (collectively called the CMG complex), which seem to play a key role in the formation and progression of replication forks. Interactions between the CMG components were observed only after the G(1)/S transition of the cell cycle and were abolished by treatment of cells with either a CDK inhibitor or siRNA against the Cdc7 kinase. Stable association of CMG required all three components of the CMG complex as well as RecQL4, Ctf4/And-1, and Mcm10. Surprisingly, depletion of TopBP1, a homologue of Dpb11 that plays an essential role in the chromatin loading of Cdc45 and GINS in yeast cells, did not significantly affect CMG complex formation. These results suggest that the proteins involved in the assembly of initiation complexes in human cells may differ somewhat from those in yeast systems. ------>tmu_sno=None ------>sno=21454 ------>authors2= ------>authors3= ------>authors4= ------>authors5= ------>authors6= ------>authors6_c= ------>authors=Huang WC ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=1 ------>updateTitle=Assembly of the Cdc45-Mcm2-7-GINS complex in human cells requires the Ctf4/And-1, RecQL4, and Mcm10 proteins. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=NULL ------>no= ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2007 ------>submit_flag=None ------>publish_month=1 |
