  1. 1. Vacuolar Ca2+-ATPases in Plants. Regulation by calmodulin binding to a N-terminal autoinhibitory domain

    Författare :Susanna Malmström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; N terminus; autoinhibitory domain; vacuole; calmodulin; calcium; plants; Ca2 -ATPase; Växtbiokemi;

    Sammanfattning : The calcium ion (Ca2+) is essential for all plant and animal life. One important function of Ca2+ is as a second messenger in the responses of the cell to environmental and hormonal signals as well as in some intrinsic developmental processes. LÄS MER

  3. 2. Damage Segregation and Cellular Rejuvenation in Saccharomyces cerevisiae

    Författare :Sandra Malmgren Hill; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aging; protein damage; quality control; metacaspase; aggregates; segregation; vacuole;

    Sammanfattning : The process of aging is defined as a time-dependent decline in cellular functionality, and aging is thought to have evolved as organisms were optimized for reproduction, at the cost of an imperfect repair and maintenance system. As a consequence, different kinds of dysfunctional components and damage accumulate over time. LÄS MER

  4. 3. Novel insights into vacuole-mediated control of plant growth and immunity

    Författare :Qinsong Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant vacuoles are organelles with numerous biological functions in growth, development, and stress responses. These include maintenance of turgor pressure, storage of minerals and proteins, and degradation of cellular content delivered by endosomal trafficking and autophagy pathways. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Cellular remodeling in response to nutrient exhaustion : From membrane contact sites to autophagy

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

    Sammanfattning : 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. LÄS MER
