  2. 1. The Plant Plasma Memrbane H+-ATPase: regulation by phosphorylation and 14-3-3 proteins

    Author : Anne Olsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phosphorylation; fusicoccin; 14-3-3; C-terminus; autoinhibitory domain; plasma membrane; plant; H -ATPase; Plant biochemistry; Växtbiokemi;

    Abstract : The plant plasma membrane H+-ATPase is a predominant membrane enzyme that provides the energy for secondary active transport across the plasma membrane. Consequently, the H+-ATPase is thought to play a major role in many cell processes, and it is implicated to be regulated by a number of factors, including hormones, blue light, and fungal toxins The plant plasma membrane H+-ATPase is regulated via an autoinhibitory domain located within the C-terminal region of the enzyme.

  4. 2. Regulatory Functions of Protein Phosphorylation in Plant Photosynthetic Membranes

    Author : Rikard Fristedt; Alexander Vener; Thomas Pfannschmidt; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Oxygenic photosynthesis is the process in plants, algae and cyanobacteria which converts light energy from the sun into carbohydrates and at the same time produces oxygen from water. Both carbohydrates and oxygen are essential to sustain life on earth. READ MORE

  5. 3. Regulatory mechanisms of amino acid-induced signaling in Saccharomyces cerevisiae

    Author : Deike J. Omnus; Per O. Ljungdahl; Claudio De Virgilio; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; regulatory mechanisms; nutrient sensing; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : This thesis describes studies aimed at elucidating the molecular mechanisms that regulate the SPS (Ssy1-Ptr3-Ssy5) signal transduction pathway in the yeast Saccharomyces cerevisiae. This pathway is induced by extracellular amino acids and facilitates their uptake. READ MORE

  6. 4. Regulation of tubulin heterodimer partitioning during interphase and mitosis

    Author : Per Holmfeldt; Martin Gullberg; Pontus Aspenström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microtubule; mitotic spindle; signal transduction; phosphorylation; cancer; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The microtubule cytoskeleton, which consists of dynamic polymers of alpha/beta tubulin heterodimers, organizes the cytoplasm and is essential for chromosome segregation during mitosis. My thesis addresses the significance and potential interplay between four distinct microtubule-regulatory proteins. READ MORE

  7. 5. Understanding molecular mechanisms of protein tyrosine kinases by molecular dynamics and free energy calculations

    Author : Yaozong Li; Kwangho Nam; Magnus Wolf-Watz; Amedeo Caflisch; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kinase; IRK; IGF-1RK; phosphorylation; activation loop; molecular dynamics; phosphoryl transfer; alchemical free energy; dynamical network; correlation map; PCA; motion projection; Gaussian softcore; free energy landscape; kinase catalysis;

    Abstract : Background: Insulin receptor kinase (IRK) and Insulin-like growth factor 1 receptor kinase (IGF-1RK) are two important members in the large class of tyrosine kinase receptors. They play pivotalroles in the regulation of glucose homeostasis, cell proliferation, differentiation, motility, andtransformation. READ MORE
