  1. 1. Adipocyte phosphatases and the antilipolytic action of insulin

    Författare :Svante Resjö; Signaltransduktionsforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein phosphorylation; protein purification; adipose tissue; PP2A; protein phosphatase; PDE3B; phosphodiesterase 3B; Insulin signalling; antilipolysis; Klinisk biologi; Clinical biology; PKB; protein kinase B;

    Sammanfattning : Adipose tissue is the main site of energy storage of the body and an important endocrine organ. Knowledge of the regulation of fat metabolism and the endocrine factors secreted by the adipocyte is crucial for the understanding of diseases such as obesity and diabetes. Insulin is the main antilipolytic hormone. LÄS MER

  2. 2. Studies on Phosphohistidine Phosphatase 1 : What? Where? Why?

    Författare :Ulla Beckman Sundh; Pia Ek; Örjan Zetterqvist; Jin-ping Li; Christian Hedberg; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PHPT1; Phosphohistidine phosphatase; PHP; Assay; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Phosphohistidine phosphatase 1 (PHPT1) is a small protein, consisting of 125 amino acids, that catalyzes the dephosphorylation of histidine but does not have any activity towards other phosphorylated amino acids. PHPT1 was identified in 2002, and is so far the only mammalian histidine phosphatase known, but still little is known about its physiological role. LÄS MER

  3. 3. Protein kinases and phosphatases in B-cell lymphoma

    Författare :Marie Fridberg; Tumörmikromiljö; []
    Nyckelord :HePTP; PTEN; PKC-beta 2; B-cell; lymphoma; kinases; ZAP70; phosphatase; SHP2;

    Sammanfattning : Around 2000 persons are diagnosed with lymphoma in Sweden each year. There are many subgroups described for this form of cancer and the great majority is derived from B-cells. The most common subgroup is Diffuse large B-cell lymphoma (DLBCL), a highly aggressive disease where only half of the patients are cured. LÄS MER

  4. 4. Promiscuity and Selectivity in Phosphoryl Transferases

    Författare :Alexandre Barrozo; Shina Kamerlin; Qiang Cui; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; phosphate chemistry; linear free energy relationships; phosphatase; catalytic promiscuity; empirical valence bond approach; alkaline phosphatase;

    Sammanfattning : Phosphoryl transfers are essential chemical reactions in key life processes, including energy production, signal transduction and protein synthesis. They are known for having extremely low reaction rates in aqueous solution, reaching the scale of millions of years. LÄS MER

  5. 5. The Membrane-Spanning Domain of Complex I Investigated with Fusion Protein Techniques

    Författare :Maria Trane; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NuoN; NuoM; NuoL; covalent bound heme; Bacillus subtilis; Escherichia coli; membrane protein; His-tag; Cytochrome c; NADH:quinone oxidureductase; fusion protein;

    Sammanfattning : NADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards the quinone binding site(s).
