Title: Targeted De Novo Centromere Formation in Drosophila Reveals Plasticity and Maintenance Potential of CENP-A Chromatin.
The data show that Drosophila CENP-A has no intrinsic specificity for centromeric chromatin and utilizes separate loading mechanisms for its incorporation into centromeric and ectopic sites. This suggests that the specific association and availability of CENP-A interacting factors are the major determinants of CENP-A loading specificity.
Title: Localization of Drosophila CENP-A to non-centromeric sites depends on the NuRD complex.
Modulation of the phosphorylation state of S20 may provide the cells with a means to fine-tune CENP-A levels in order to prevent deleterious loading to extra-centromeric sites.
Title: Phosphorylation of Drosophila CENP-A on serine 20 regulates protein turn-over and centromere-specific loading.
CENP-A levels inversely correlate with mitosis duration suggesting crosstalk of CENP-A loading with the regulatory machinery of mitosis. Mitosis length is influenced by the spindle assembly checkpoint (SAC), and authors found that CAL1 interacts with the SAC protein and RZZ complex component Zw10 and thus constitutes the anchor for the recruitment of RZZ.
Title: The checkpoint protein Zw10 connects CAL1-dependent CENP-A centromeric loading and mitosis duration in Drosophila cells.
results suggest that, whereas SCF(Ppa) targets the fraction of CENP-A(CID) that is not in complex with Cal1, APC/C(Cdh1) mediates also degradation of the Cal1-CENP-A(CID) complex and, thus, likely contributes to the regulation of centromeric CENP-A(CID) deposition
Title: The E3-ligases SCFPpa and APC/CCdh1 co-operate to regulate CENP-ACID expression across the cell cycle.
Cid duplication (leading to Cid6) within the Drosophila subgenus and show that not only Cid, but also Cenp-C is duplicated in the entire subgenus.

NLP and HMR largely co-localize in domains that are immediately adjacent to, yet distinct from centromere domains defined by the centromeric histone dCENP-A.
Title: Oligomerization of Drosophila Nucleoplasmin-Like Protein is required for its centromere localization.
