    Epigenetic regulation of lateralized fetal spinal gene expression underlies hemispheric asymmetries

    Sebastian Ocklenburg et al.
    Gene expression asymmetries in fetal spinal cord are triggered by epigenetic mechanisms suggesting that handedness has a spinal instead of a cortical origin.

    CDK-regulated dimerization of M18BP1 on a Mis18 hexamer is necessary for CENP-A loading

    Dongqing Pan et al.
    The stoichiometry and mechanism of interactions of the Mis18 complex with M18BP1 was analysed to unveil the molecular basis of new CENP-A deposition during the G1 phase of the cell cycle.

    The LIM protein complex establishes a retinal circuitry of visual adaptation by regulating Pax6 α-enhancer activity

    Yeha Kim et al.
    Regulation of Pax6 expression through the α-enhancer fine-tunes amacrine cell subtype number, and consequently, the visual output of the retina.

    Stella modulates transcriptional and endogenous retrovirus programs during maternal-to-zygotic transition

    Yun Huang et al.
    Soon after fertilisation, a critical portion of the embryonic genome is switched on through the actions of maternally inherited Stella, in part through controlling the activation of transposable elements.

    Two-way communication between SecY and SecA suggests a Brownian ratchet mechanism for protein translocation

    William John Allen et al.
    Evidence is presented that supports a completely new, diffusion-driven mechanism for transporting proteins across membranes in bacteria.

    Architecture and RNA binding of the human negative elongation factor

    Seychelle M Vos et al.
    The structural architecture of the 4-subunit, RNA-binding human negative elongation factor NELF is derived by a combination of X-ray crystallography and protein crosslinking.

    Analysis of cellular behavior and cytoskeletal dynamics reveal a constriction mechanism driving optic cup morphogenesis

    María Nicolás-Pérez et al.
    High-resolution live imaging analysis shows a constriction mechanism that drives zebrafish optic cup morphogenesis and highlights the role of the extracellular matrix in transmitting tensions beyond the cellular level.

    NOVA regulates Dcc alternative splicing during neuronal migration and axon guidance in the spinal cord

    Janelle C Leggere et al.
    Alternative splicing of the Dcc gene, which is controlled by the NOVA RNA-binding proteins, is crucial during neuronal migration and axon guidance.

    Cortex commands the performance of skilled movement

    Jian-Zhong Guo et al.
    Optogenetic inhibition demonstrates that the cortex is necessary and sufficient for the initiation and execution of a learned, skilled action.

    HOPS recognizes each SNARE, assembling ternary trans-complexes for rapid fusion upon engagement with the 4th SNARE

    Hongki Song et al.
    The tethering complex HOPS employs affinity for each of the 4 SNAREs to catalyze assembly of 3-SNARE intermediates, supporting an immediate burst of membrane fusion triggered by the 4th SNARE.
