  2. 1. Interorganellar connectivity : From protein to lipid homeostasis

    Author : Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

  4. 2. Cellular remodeling in response to nutrient exhaustion : From membrane contact sites to autophagy

    Author : Mahsa Ebrahimi; Sabrina Büttner; Cristina Mazzoni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aging and longevity; yeast; phosphate restriction; interorganellar communication; autophagy; MVB pathway; NVJs; lipid droplets; nutritional regimes; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Adaptation to fluctuating environments is critical for cellular fitness and survival. Cells need to sense changes in their surroundings and quickly adjust cellular homeostasis and metabolism accordingly. READ MORE

  5. 3. A molecular chaperone that governs membrane contact sites and lipid metabolism

    Author : Sergi Tosal Castaño; Sabrina Büttner; W. Mike Henne; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Yeast; nucleus-vacuole junctions; proteostasis; unfolded protein response; fatty acid elongation; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Transmembrane proteins represent almost one third of the total cellular proteome, and the majority of them requires translocation into the endoplasmic reticulum (ER) to be folded, sorted and transported to their final subcellular destination. High translational rates during exponential cell growth result in a massive influx of immature proteins into the ER, requiring rapid and accurate folding. READ MORE
