    Quantitative analysis of mammalian GIRK2 channel regulation by G proteins, the signaling lipid PIP2 and Na+ in a reconstituted system

    Weiwei Wang et al.
    The G protein subunits Gβγ and the signaling lipid PIP2 are simultaneously needed to activate the potassium ion channel GIRK2 to control the voltage across a lipid bilayer, while sodium ions modulate these molecules' effects.

    GRAM domain proteins specialize functionally distinct ER-PM contact sites in human cells

    Marina Besprozvannaya et al.
    Functionally distinct ER-PM domains in human cells are defined by conserved GRAM domain containing proteins.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu et al.
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    Structural mechanisms of phospholipid activation of the human TPC2 channel

    Ji She et al.
    Cryo-EM structures of human TPC2 channel in the ligand-bound and apo states reveal the structural mechanism of PI(3,5)P2 lipid regulated gating of TPC2.

    PI(3,5)P2 biosynthesis regulates oligodendrocyte differentiation by intrinsic and extrinsic mechanisms

    Yevgeniya A Mironova et al.
    The signaling lipid PI(3,5)P2 supports the formation of the myelin sheath, by regulating trafficking of myelin building blocks within oligodendrocytes and communication between oligodendrocytes and neuronal axons.

    Biofilms: Take my breath away

    Vinai C Thomas, Paul D Fey
    A lack of oxygen activates a pathway that causes the bacterial cell wall to break down, which, in turn, aids bacterial biofilm development.

  1. Meta-Research: How significant are the public dimensions of faculty work in review, promotion and tenure documents?

    Juan P Alperin et al.
    An analysis of review, promotion and tenure documents from 129 US and Canadian universities suggests institutions could better fulfill their public missions by changing how they incentivize the public dimensions of faculty work.
  2. Research: Financial costs and personal consequences of research misconduct resulting in retracted publications

    Andrew M Stern et al.
    In the first study attempting to formally quantify the deleterious impact of research misconduct on funding sources and publication output, we found that misconduct accounts for a small but substantial portion of American biomedical science funding dollars and damages the productivity and rate of funding acquisition of those who commit misconduct.
