    Crystal structures of the CPAP/STIL complex reveal its role in centriole assembly and human microcephaly

    Matthew A Cottee, Nadine Muschalik ... Mark van Breugel
    Structural analyses of the centriole proteins CPAP and STIL identify domains that are critical for centriole formation and provide a structural explanation for a mutation that causes human microcephaly.

    The structure of the Ctf19c/CCAN from budding yeast

    Stephen M Hinshaw, Stephen C Harrison
    Reconstitution and cryo-EM reconstruction of the yeast Ctf19 complex (constitutive centromere associated network, or CCAN, in other organisms) shows how inner kinetochore proteins assemble.

    Condensin I subunit Cap-G is essential for proper gene expression during the maturation of post-mitotic neurons

    Amira Hassan, Pablo Araguas Rodriguez ... Tony D Southall
    The condensin I subunit Cap-G is expressed in post-mitotic neurons and its removal, especially from less mature neurons, results in gene expression changes, reduced survival and behavioural defects in Drosophila.

    Differential requirements for cyclase-associated protein (CAP) in actin-dependent processes of Toxoplasma gondii

    Alex Hunt, Matthew Robert Geoffrey Russell ... Moritz Treeck
    Partially overlapping functions of a limited subset of actin binding proteins allow the parasite Toxoplasma gondii to achieve actin regulation required for complex cellular processes.

    Metal microdrive and head cap system for silicon probe recovery in freely moving rodent

    Mihály Vöröslakos, Peter C Petersen ... György Buzsáki
    A reusable system of 3D printed stainless steel microdrive and plastic head cap allows stable recording of electrophysiological data in mice and rats and easy recovery of silicon probes.

    The speed of GTP hydrolysis determines GTP cap size and controls microtubule stability

    Johanna Roostalu, Claire Thomas ... Thomas Surrey
    GTPase-deficient microtubules are hyper-stable and have longer EB binding regions, demonstrating that EBs bind the GTP cap.

    La-related protein 1 (LARP1) binds the mRNA cap, blocking eIF4F assembly on TOP mRNAs

    Roni M Lahr, Bruno D Fonseca ... Andrea J Berman
    La-related protein 1 specifically and directly binds the 5' cap and first nucleotide of mRNAs encoding ribosomal proteins and translation factors, inhibiting the assembly of translation initiation factors on these messages and therefore their translation.

    A novel role for the root cap in phosphate uptake and homeostasis

    Satomi Kanno, Jean-François Arrighi ... Laurent Nussaume
    Real-time 33P imaging combined with specific complementation of inorganic phosphate transport in the root cap reveals this tissue’s contribution to phosphate uptake.

    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego, Fernando Josa-Prado ... Maria A Oliva
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.

    The size of the EB cap determines instantaneous microtubule stability

    Christian Duellberg, Nicholas I Cade ... Thomas Surrey
    The EB binding region defines the length of the protective cap that stabilizes growing microtubules.
