    The synaptonemal complex has liquid crystalline properties and spatially regulates meiotic recombination factors

    Ofer Rog et al.
    Formation of a phase-separated interface between homologous chromosomes during meiosis enables regulatory signals to spread in cis over long distances, illuminating the longstanding mystery of crossover interference.

    Deconstruction of the Ras switching cycle through saturation mutagenesis

    Pradeep Bandaru et al.
    Sequence conservation in Ras depends strongly on the biochemical network in which it operates, providing a framework for understanding the origin of global selection pressures on proteins.

    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.

    A visual circuit uses complementary mechanisms to support transient and sustained pupil constriction

    William Thomas Keenan et al.
    A single class of neurons switches both its sensory detection and neurotransmission mechanisms to support transient or sustained physiological output.

    RAL GTPases mediate EGFR-driven intestinal stem cell proliferation and tumourigenesis

    Máté Nászai et al.
    Combined genetic experiments and cellular trafficking assays in Drosophila and mammalian models uncover a new role of RAS-like GTPases in EGFR signalling activation during tissue regeneration and tumourigenesis through regulation of EGFR internalisation.

    Sensitivity and kinetics of signal transmission at the first visual synapse differentially impact visually-guided behavior

    Ignacio Sarria et al.
    Adjusting key parameters of the synaptic transmission at a single defined synapse of the visual circuit can affect properties of this circuit and animal behavior.

    Membrane interactions of the globular domain and the hypervariable region of KRAS4b define its unique diffusion behavior

    Debanjan Goswami et al.
    Compared to other isoforms of RAS, KRAS4b has unique membrane diffusion behavior related to its biology, and the two major domains of the protein both contribute to this diffusion behavior.

    Tumor suppressive role of sestrin2 during colitis and colon carcinogenesis

    Seung-Hyun Ro et al.
    Sestrin2 loss could be a universal mechanism of human colon carcinogenesis that allows for barrier dysfunction, mTORC1 hyperactivation, unrestricted tumor growth and chemoresistance.

    SIRT6 regulates Ras-related protein R-Ras2 by lysine defatty-acylation

    Xiaoyu Zhang et al.
    A posttranslational regulatory mechanism for a Ras family small GTPase could open up new directions to understand and control the Ras family of proteins that are important for physiology and diseases.

    Targeting RAS-driven human cancer cells with antibodies to upregulated and essential cell-surface proteins

    Alexander J Martinko et al.
    Proteomics and functional genomics coupled to an antibody discovery pipeline revealed the influence of oncogenic RAS signaling on the cell-surface proteome and resulted in the discovery of potential therapeutic targets for RAS-driven cancers.
