    Spatial organization shapes the turnover of a bacterial transcriptome

    Jeffrey R Moffitt et al.
    Transcriptome-scale RNA imaging and lifetime measurements reveal that the E. coli transcriptome is spatially organized and that this organization modulates the post-transcriptional fate of bacterial mRNAs.

    Analysis of protein phosphorylation in nerve terminal reveals extensive changes in active zone proteins upon exocytosis

    Mahdokht Kohansal-Nodehi et al.
    Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.

    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies et al.
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    Negative regulation of urokinase receptor activity by a GPI-specific phospholipase C in breast cancer cells

    Michiel van Veen et al.
    GDE3 is a transmembrane GPI-specific phospholipase C that sheds the urokinase receptor (uPAR) from the cell surface resulting in loss of uPAR function in breast cancer cells and reduced tumor growth.

    An unfolded protein-induced conformational switch activates mammalian IRE1

    G Elif Karagöz et al.
    ER-stress sensing mechanism of the unfolded protein response sensor/transducer IRE1 is conserved from yeast to mammals, where in mammals, unfolded protein binding to IRE1's ER lumenal domain is coupled to its oligomerization and activation through an allosteric conformational change.

    Phosphorylation-mediated PTEN conformational closure and deactivation revealed with protein semisynthesis

    David Bolduc et al.
    C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.

    The Rab6-regulated KIF1C kinesin motor domain contributes to Golgi organization

    Peter L Lee et al.
    Rab6A binds directly to both the C-terminus and the N-terminal motor domain of the kinesin KIF1C to regulate vesicle motility and Golgi organization.

    Phosphoinositides regulate force-independent interactions between talin, vinculin, and actin

    Charlotte F Kelley et al.
    In vitro reconstitution of the core focal adhesion proteins talin and vinculin with actin reveals lipid-dependent release of autoinhibition.

    Novel functions for integrin-associated proteins revealed by analysis of myofibril attachment in Drosophila

    Hannah J Green et al.
    Integrin and actin associated proteins are resolved into four layers within myofibril attachments, an architecture requiring balanced positive and negative regulation of integrin adhesion with integrated mechanotransduction and actin pathways.

    Regulation of localization and function of the transcriptional co-activator YAP by angiomotin

    Susana Moleirinho et al.
    Phosphorylation of Angiomotin regulates YAP localization and activity.
