    Cortical dynein pulling mechanism is regulated by differentially targeted attachment molecule Num1

    Safia Omer et al.
    Dynein-dependent microtubule-cortex interactions – "side-on" versus "end-on" pulling – are regulated by cortical ER and mediated by distinct pools of cortical anchor that are differentially localized along the cell periphery.

    The Nesprin-1/-2 ortholog ANC-1 regulates organelle positioning in C. elegans independently from its KASH or actin-binding domains

    Hongyan Hao et al.
    The giant KASH protein ANC-1 maintains the integrity of the cytoplasm to anchor nuclei, ER, and other organelles within the cell.

    Polo-like kinase Cdc5 regulates Spc72 recruitment to spindle pole body in the methylotrophic yeast Ogataea polymorpha

    Hiromi Maekawa et al.
    Cdc5-dependent SPB regulation is linked to delayed cytoplasmic microtubule organization in Ogataea polymorpha.

    Random sub-diffusion and capture of genes by the nuclear pore reduces dynamics and coordinates inter-chromosomal movement

    Michael Chas Sumner et al.
    Measuring and simulating chromatin dynamics reveals that repositioning of genes to the nuclear pore is neither active nor vectorial, but reduces sub-diffusion and coordinates movement between loci on different chromosomes.

    The DNA-binding protein HTa from Thermoplasma acidophilum is an archaeal histone analog

    Antoine Hocher et al.
    In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.

    A molecular mechanism for LINC complex branching by structurally diverse SUN-KASH 6:6 assemblies

    Manickam Gurusaran, Owen Richard Davies
    The LINC complex has a core 6:6 structure in which KASH-binding induces head-to-head interactions between SUN trimers, suggesting force transduction between cytoskeletal and nuclear components through branched LINC complex networks.

    Cadherins regulate nuclear topography and function of developing ocular motor circuitry

    Athene Knüfer et al.
    Cadherin-dependent cell adhesion controls the contralateral migration and clustering of ocular motor subpopulations and is required for the development of functional eye movements driven by those neurons.

    Chromosome-wide mechanisms to decouple gene expression from gene dose during sex-chromosome evolution

    Bayly S Wheeler et al.
    A chromosome-wide mechanism balances X-linked gene expression between the sexes in C. elegans, but no similar chromosome-wide mechanism balances gene expression between X chromosomes and autosomes.

    Centering and symmetry breaking in confined contracting actomyosin networks

    Niv Ierushalmi et al.
    Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.

    Cell lineage-dependent chiral actomyosin flows drive cellular rearrangements in early Caenorhabditis elegans development

    Lokesh G Pimpale et al.
    Developmentally controlled chiral counter-rotating actomyosin flows drive cell-lineage spindle skews and cell rearrangements during cytokinesis in early nematode development.
