    ..These data offer direct support for centromere identity maintained by a unique nucleosome that serves to distinguish the centromere from the rest of the chromosome. ..

    ..Our results indicate that the regions of CENP-A required for early events in centromere establishment differ from those that are required for maintaining centromere identity. ..

    ..Our molecular model explains how PARP-1 DNA damage detection leads to local unfolding of the HD that relieves autoinhibition, and has important implications for the design of PARP inhibitors. ..

    ..Thus, the remarkable stability of CENP-A nucleosomes confers transgenerational centromere identity in mammals. ..

    ..Lastly, we describe our approach to assemble and analyze a complex between the recombinant human CENP-A nucleosome and one of its binding partners, CENP-C. ..

    ..CENP-C depletion leads to rapid removal of CENP-A from centromeres, indicating their collaboration in maintaining centromere identity. ..

    ..We find that Cdk-mediated inhibition is exerted by sequestering active factors away from the centromere. Finally, we show that displacement of M18BP1 from the centromere is critical for the assembly mechanism of CENP-A. ..

    ..Thus, neither Ser68 nor Lys124 post-translational modification is essential for long-term centromere identity, propagation, cell-cycle-dependent deposition, maintenance, function, or mediation of early steps in centromere establishment. ..

    ..We propose that amplified repetitive sequences act as selfish elements by promoting expansion of CENP-A chromatin and increased transmission through the female germline. ..
