TranscriptomicsDisplacement and re-accumulation of centromeric cohesin during transient pre-anaphase centromere splitting
The ring-shaped cohesin complex links sister chromatids until their timely segregation during mitosis. Cohesin is enriched at centromeres, where it provides the cohesive counter-force to bi-polar tension produced by the mitotic spindle. As a consequence of spindle tension, centromeric sequences tran...

TranscriptomicsTop1 and Top2-mediated replication fork integrity
DNA topoisomerases solve topological problems during chromosome metabolism. We investigated where and when Top1 and Top2 are recruited on replicating chromosomes and how their inactivation affects fork integrity and DNA damage checkpoint activation. We show that, in the context of replicating chroma...

TranscriptomicsReplication and Protein binding profile of chromosome VI of S.cerevisiae
Type of experiment: ChIP-chip (Chromatin immunoprecipitation on DNA chip) analyses of replication related, checkpoint related proteins and BrdU incorporated regions at 300bp resolution. Newly developed S.cerevisiae chromosome VI tiling array produced by affymetrix was used. Experimental factors:Dis...

TranscriptomicsKinetochores coordinate pericentromeric cohesion and early DNA replication by Cdc7-Dbf4 kinase recruitment
Centromeres play several important roles in ensuring proper chromosome segregation. Not only do they promote kinetochore assembly for microtubule attachment, but they also support robust sister chromatid cohesion at pericentromeres and facilitate replication of centromeric DNA early in S phase. Howe...
