    A new class of disordered elements controls DNA replication through initiator self-assembly

    Matthew W Parker et al.
    DNA replication initiation proteins contain a disordered domain that impacts each stage of their function, from chromatin recruitment and initiator co-assembly to the subsequent displacement of the factors from chromatin.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

    Release of cholesterol-rich particles from the macrophage plasma membrane during movement of filopodia and lamellipodia

    Xuchen Hu et al.
    Macrophages release 30-nm vesicular particles enriched in accessible cholesterol during cellular locomotion, a discovery that is likely relevant to cholesterol disposal by these cells.

    Mechanisms of iron- and O2-sensing by the [4Fe-4S] cluster of the global iron regulator RirA

    Ma Teresa Pellicer Martinez et al.
    Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O2 are revealed by mass spectrometry and spectroscopy.

    Single molecule mechanics resolves the earliest events in force generation by cardiac myosin

    Michael S Woody et al.
    Cardiac myosin converts energy from ATP into mechanical work by transitioning from a short-lived force-bearing state, to a post working stroke state before the release of inorganic phosphate.

    Heparan sulfates are critical regulators of the inhibitory megakaryocyte-platelet receptor G6b-B

    Timo Vögtle et al.
    Heparan sulfates in the vessel wall bind and regulate signaling from the megakaryocyte/platelet-specific inhibitory receptor G6b-B, a critical regulator of platelet homeostasis.

    Oxygen Sensors: When is a target not a target?

    David C Bersten, Daniel J Peet
    Cells rely on prolyl hydroxylase enzymes to sense low levels of oxygen, but they might act on fewer targets than previously thought.

    Lack of activity of recombinant HIF prolyl hydroxylases (PHDs) on reported non-HIF substrates

    Matthew E Cockman et al.
    Assays using recombinant HIF prolyl hydroxylases did not support hydroxylation of more than 20 reported non-HIF substrates under conditions where robust HIF hydroxylation was observed.
