    Resveratrol modulates the inflammatory response via an estrogen receptor-signal integration network

    Jerome C Nwachukwu, Sathish Srinivasan ... Kendall W Nettles
    Anti-inflammatory effects of resveratrol are mediated by the estrogen receptor to coordinate a complex array of transcriptional coregulators, suggesting that estrogenic effects must be considered in the complex polypharmacology of resveratrol.

    AFF4 binding to Tat-P-TEFb indirectly stimulates TAR recognition of super elongation complexes at the HIV promoter

    Ursula Schulze-Gahmen, Huasong Lu ... Tom Alber
    AFF4 increases the combined selectivity of HIV Tat and TAR for super elongation complexes 330-fold over P-TEFb alone.

    Periodic DNA patrolling underlies diverse functions of Pif1 on R-loops and G-rich DNA

    Ruobo Zhou, Jichuan Zhang ... Taekjip Ha
    Analyzing single molecules reveals that Pif1 family helicases periodically patrol DNA, which may explain this enzyme's ability to suppress genome instability at G-quadruplex motifs and transcriptional RNA-DNA hybrids (R-loops).

    Symmetry breaking in reconstituted actin cortices

    Enas Abu Shah, Kinneret Keren
    A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.

    Structural basis for the assembly of the mitotic motor Kinesin-5 into bipolar tetramers

    Jessica E Scholey, Stanley Nithianantham ... Jawdat Al-Bassam
    The Bipolar Assembly domain of kinesin-5 comprises an anti-parallel four-helix bundle, which explains how kinesin-5 subunits assemble into bipolar tetramers with two motile ends that transmit forces while crosslinking and sliding adjacent microtubules during mitosis.

    Encounter complexes and dimensionality reduction in protein–protein association

    Dima Kozakov, Keyong Li ... Sandor Vajda
    Analysis of protein–protein encounter complexes shows that proteins associate along preferred pathways, similar to the sliding of a protein along DNA.

    A conserved MCM single-stranded DNA binding element is essential for replication initiation

    Clifford A Froelich, Sukhyun Kang ... Eric J Enemark
    The crystal structure of the MCM helicase bound to single-stranded DNA reveals a binding motif that is critical for cell viability, helicase activation and DNA replication.

    Phosphoinositide-mediated oligomerization of a defensin induces cell lysis

    Ivan KH Poon, Amy A Baxter ... Mark D Hulett
    A novel innate defense mechanism of cell lysis involves the coordinated oligomerization of a defensin by interaction with the membrane lipid, phosphatidylinositol 4,5-bisphosphate.
