    A stress assembly that confers cell viability by preserving ERES components during amino-acid starvation

    Margarita Zacharogianni et al.
    Amino-acid starvation leads to the formation of a reversible stress assembly, the Sec body, which is a pro-survival reservoir for components of the ER exit sites.

    AMPK and vacuole-associated Atg14p orchestrate μ-lipophagy for energy production and long-term survival under glucose starvation

    Arnold Y Seo et al.
    Upon AMPK activation by acute glucose restriction, Atg14p shifts its distribution from ER exit sites to liquid-ordered membrane domains on the vacuolar surface where, together with Atg6p, it facilitates LD-specific autophagy (i.e., microautophagy of lipid droplets) for energy production and long-term survival of starved cells.

    Super-resolution microscopy reveals majorly mono- and dimeric presenilin1/γ-secretase at the cell surface

    Abril Angélica Escamilla-Ayala et al.
    Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.

    Regulation of nerve growth and patterning by cell surface protein disulphide isomerase

    Geoffrey MW Cook et al.
    The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.

    The GTPase Nog1 co-ordinates the assembly, maturation and quality control of distant ribosomal functional centers

    Purnima Klingauf-Nerurkar et al.
    The GTPase Nog1 orchestrates stalk assembly, peptidyl transferase centre maturation and polypeptide exit tunnel quality control.

    The manifold actions of signaling peptides on subcellular dynamics of a receptor specify stomatal cell fate

    Xingyun Qi et al.
    A binary cell fate decision to be or not to be stomata is regulated by multiple peptide ligands, each triggering a unique subcellular dynamics of their shared receptor.

    Multiplexed measurement of variant abundance and activity reveals VKOR topology, active site and human variant impact

    Melissa A Chiasson et al.
    Human vitamin K epoxide reductase (VKOR) has a four transmembrane domain topology that supports the use of a homology model, enabling identification of active site residues and human variant impact.
