    Structural basis of phosphatidylcholine recognition by the C2–domain of cytosolic phospholipase A2α

    Yoshinori Hirano, Yong-Guang Gao ... Rhoderick E Brown
    The C2-domain of cytoplasmic phospholipase A2α is structurally designed to target PC-rich membrane regions to increase the enzymatic efficiency of the catalytic domain, which prefers PCs with polyunsaturated acyl chains.

    Symmetry transitions during gating of the TRPV2 ion channel in lipid membranes

    Lejla Zubcevic, Allen L Hsu ... Seok-Yong Lee
    Ligand-induced two-fold symmetric arrangement in TRPV2 is observed in the native-like nanodisc-reconstituted condition using cryo-electron microscopy.

    Regulatory switch at the cytoplasmic interface controls TRPV channel gating

    Lejla Zubcevic, William F Borschel ... Seok-Yong Lee
    C-terminal domain of thermoTRPV channels regulates channel gating at the cytoplasmic interface through a switch-like process.

    An order-to-disorder structural switch activates the FoxM1 transcription factor

    Aimee H Marceau, Caileen M Brison ... Seth M Rubin
    Structural and biochemical analysis reveals that two intrinsically disordered domains of the transcription factor FoxM1 co-fold to form an autoinhibited conformation, which is disrupted by a specific activating phosphorylation event.

    Neck linker docking is critical for Kinesin-1 force generation in cells but at a cost to motor speed and processivity

    Breane G Budaitis, Shashank Jariwala ... Kristen J Verhey
    Force generation by kinesin motor proteins requires formation of both a 2-stranded cover-neck bundle and an asparagine-based latch for transport of membrane-bound cargoes in cells.

    Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

    Yuling Li, Jinhan Zhou ... Qingxiang Sun
    Animal RanBP1 nuclear export and cargo dissociation mechanisms are surprisingly different from yeast, due to mutations of critical residues, leading to greater nuclear transport efficiency and higher energy cost.

    Intrinsically aggregation-prone proteins form amyloid-like aggregates and contribute to tissue aging in Caenorhabditis elegans

    Chaolie Huang, Sara Wagner-Valladolid ... Della C David
    Age-dependent protein aggregation closely resembles protein aggregation associated with neurodegenerative diseases and other amyloidoses, and initiates early functional decline in different tissues.

    Evidence for DNA-mediated nuclear compartmentalization distinct from phase separation

    David Trombley McSwiggen, Anders S Hansen ... Xavier Darzacq
    Transient DNA interactions by DNA-binding proteins are utilized by herpes simple virus as an alternative route to generate membraneless compartments in the nucleus without invoking phase separation.

    The Cas4-Cas1-Cas2 complex mediates precise prespacer processing during CRISPR adaptation

    Hayun Lee, Yukti Dhingra, Dipali G Sashital
    During CRISPR adaptation, Cas4 forms a ternary complex with the Cas1-Cas2 spacer integration complex, an interaction that coordinates substrate hand-off following precise, PAM-dependent prespacer processing prior to integration.

    Microsecond sub-domain motions and the folding and misfolding of the mouse prion protein

    Rama Reddy Goluguri, Sreemantee Sen, Jayant Udgaonkar
    Native state dynamics of mouse prion protein were measured, and these motions were shown to be having a role in initiation of aggregation.
