    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    Spatiotemporal regulation of autophagy during Caenorhabditis elegans aging

    Jessica T Chang et al.
    Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.

    ESCRTs function directly on the lysosome membrane to downregulate ubiquitinated lysosomal membrane proteins

    Lu Zhu et al.
    The lysosome membrane is a new functional location for the ESCRTs in yeast.

    Transcription factor TFCP2L1 patterns cells in the mouse kidney collecting ducts

    Max Werth et al.
    A combination of genetic and molecular assays revealed that transcription factor Tfcp2l1 provides the basis for cell patterning and physiologic coordination in kidney collecting ducts.

    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.

    Identification of cryptic subunits from an apicomplexan ATP synthase

    Diego Huet et al.
    A phylum-specific ATP synthase subunit is needed for proper mitochondrial function and stability of the complex in Toxoplasma gondii.

    Molecular mechanism to target the endosomal Mon1-Ccz1 GEF complex to the pre-autophagosomal structure

    Jieqiong Gao et al.
    The endosomal GEF Mon1-Ccz1 binds to Atg8 on autophagosomes, and recruits its substrate, the Rab7-like Ypt7, which then mediates fusion of the autophagosomes with the lysosome.

    Heat stress promotes longevity in budding yeast by relaxing the confinement of age-promoting factors in the mother cell

    Sandro Baldi et al.
    To promote longevity under heat stress shares yeast aging factors with progeny through a down-regulation of the diffusion barrier in the membranes between the mitotic cells.

    Sec24 phosphorylation regulates autophagosome abundance during nutrient deprivation

    Saralin Davis et al.
    Phosphorylation of a core trafficking component, the COPII coat subunit Sec24, regulates cross-talk between the secretory and autophagy machinery during starvation.
