The histone H3 variant, CENP-ACnp1, is normally assembled upon canonical centromeric sequences, but there is no apparent obligate coupling of sequence and assembly, suggesting that centromere location can be epigenetically determined. To explore the tolerances and constraints on CENP-ACnp1 depositio...
ORGANISM(S): Schizosaccharomyces pombe 
We performed single-cell RNA-Seq to determine the effects of CENP-A overexpression and p53 status on cell fate over time. We established clonal MCF10-2A TetOn-CENPA-FLAG-HA cell lines where CENP-A can be reversibly induced by Doxycycline (Dox) treatment. We compared prolonged, continuous CENP-A over...

We employ the well-studied fission yeast centromere to investigate the function of the CENP-A (Cnp1) N-tail. We show that alteration of the N-tail did not affect Cnp1 loading at centromeres, outer kinetochore formation, or spindle checkpoint signaling, but nevertheless elevated chromosome loss. N-Ta...

ChIP-seq of CENP-A in S. pombe

CENP-A, the centromeric histone H3 variant, is essential for the proper segregation of human chromosomes to daughter cells. High CENP-A expression leads to the misincorporation of CENP-A in non-centromeric chromatin and can promote an epithelial-mesenchymal transition (EMT). Here, we explored how C...
ORGANISM(S): Homo sapiens 
Specialized chromatin containing CENP-A nucleosomes instead of H3 nucleosomes is found at all centromeres. However, the mechanisms that specify the locations at which CENP-A chromatin is assembled remain elusive in organisms with regional, epigenetically regulated centromeres. It is known that norma...

Centromeres are essential to ensure proper chromosome segregation in eukaryotes. Their definition relies on the presence of a centromere-specific H3 histone variant CenH3, known as CENP-A in mammals. Its overexpression in aggressive cancers raises questions concerning its effect on chromatin dynamic...
ORGANISM(S): Homo sapiens 
We performed bulk RNA-Seq to investigate global transcriptional changes upon overexpression of the centromeric H3 variant CenH3/CENP-A in p53 wild-type and defective cells, and after X-irradiation treatment. We established clonal MCF-10-2A TetOn-CENPA-FLAG-HA cell lines where CENP-A can be reversibl...
