    Metabolic constraints drive self-organization of specialized cell groups

    Sriram Varahan et al.
    In a developing yeast colony, cells go from homogeneous states to spatially organized, specialized metabolic states, and the new metabolic states depend on resources produced by the original state.

    A critical role of VMP1 in lipoprotein secretion

    Hideaki Morishita et al.
    The ER transmembrane protein VMP1 is important for release of lipoproteins from the ER membrane into the ER lumen for secretion.

    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills et al.
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    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.

    Chemotactic network responses to live bacteria show independence of phagocytosis from chemoreceptor sensing

    Netra Pal Meena, Alan R Kimmel
    Eukaryotic chemotaxis to live bacteria was quantified at a high throughput level, for the first time, and mechanistically examined for the interrelationship between chemotaxis and phagocytosis.

    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz et al.
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    Aerotaxis in the closest relatives of animals

    Julius B Kirkegaard et al.
    The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.

    Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

    Mirko Messa et al.
    Epsin has a key role in the coupling of actin to endocytic clathrin coated pits that is required for their maturation and helps capture SNAREs at endocytic clathrin coated pits.

    Lis1 regulates dynein by sterically blocking its mechanochemical cycle

    Katerina Toropova et al.
    Structural and functional studies reveal how a ubiquitous regulator of dynein keeps the microtubule-based motor in a persistent track-bound state.

    Cytoplasmic dynein crosslinks and slides anti-parallel microtubules using its two motor domains

    Marvin E Tanenbaum et al.
    The motor domains of dynein are sufficient to crosslink microtubules and slide them antiparallel to each other.
