    Imaging the fate of histone Cse4 reveals de novo replacement in S phase and subsequent stable residence at centromeres

    Jan Wisniewski, Bassam Hajj ... Carl Wu
    Internally tagged, functional Cse4/CENP-A/CenH3 histone variant is exclusively centromeric and stable through the budding yeast cell cycle after replacement in S phase.

    A long non-coding RNA is required for targeting centromeric protein A to the human centromere

    Delphine Quénet, Yamini Dalal
    A non-coding RNA-based targeting mechanism could potentially epigenetically maintain specialized chromatin structures, such as the centromere, in vivo.

    Spatial inter-centromeric interactions facilitated the emergence of evolutionary new centromeres

    Krishnendu Guin, Yao Chen ... Kaustuv Sanyal
    Proximity and homology guided inter-chromosomal translocations drive karyotype evolution.

    Heat stress impairs centromere structure and segregation of meiotic chromosomes in Arabidopsis

    Lucie Crhak Khaitova, Pavlina Mikulkova ... Karel Riha
    The sensitivity of Arabidopsis meiotic centromeres to heat stress suggests that centromere function is one of the key determinants of plant reproduction under rising temperatures.

    Mitotic progression, arrest, exit or death relies on centromere structural integrity, rather than de novo transcription

    Marco Novais-Cruz, Maria Alba Abad ... Cristina Ferrás
    Direct live-cell imaging of human cells, combined with RNA-seq, qPCR and in vitro reconstitution essays, reveal that mitotic progression, arrest, exit or death is independent of de novo transcription.

    The pseudo GTPase CENP-M drives human kinetochore assembly

    Federica Basilico, Stefano Maffini ... Andrea Musacchio
    Centromeric protein M (CENP-M) is required for the stabilization of a quaternary complex that plays a crucial role in kinetochore organization and function.

    Centromere deletion in Cryptococcus deuterogattii leads to neocentromere formation and chromosome fusions

    Klaas Schotanus, Joseph Heitman
    Centromere deletion in Cryptococcus deuterogattii results in neocentromeres, which span actively expressed genes and at elevated temperatures cen10∆ mutants are unstable leading to chromosome fusion and silencing of the neocentromere.

    Structural evidence for Scc4-dependent localization of cohesin loading

    Stephen M Hinshaw, Vasso Makrantoni ... Stephen C Harrison
    Cohesin loading at centromeres depends on a conserved surface cluster of amino-acid residues on the cohesin loading protein, Scc4.

    An asymmetric centromeric nucleosome

    Yuichi Ichikawa, Noriko Saitoh, Paul D Kaufman
    Centromeric histones, the foundation for accurate chromosome segregation, have now been re-engineered to allow for analysis of the stoichiometry of required domains.

    Recurrent loss of CenH3 is associated with independent transitions to holocentricity in insects

    Ines A Drinnenberg, Dakota deYoung ... Harmit Singh Malik
    CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.
