  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

  3. 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 :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

  4. 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

  5. 4. Promiscuity and Selectivity in Phosphoryl Transferases

    Författare :Alexandre Barrozo; Shina Kamerlin; Qiang Cui; Uppsala universitet; []
    Nyckelord :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

  7. 5. Membrane and secretory protein production in Escherichia coli

    Författare :Alexandros Karyolaimos; Jan-Willem de Gier; Matthew DeLisa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; recombinant protein; tunable protein production; cytoplasmic membrane; periplasm; signal peptide; force profile analysis; co-translational folding; Biochemistry; biokemi;

    Sammanfattning : Escherichia coli (E. coli) is the most widely used bacterium for the production of recombinant proteins. However, the production of proteins in its cytoplasmic membrane or periplasm is challenging. Therefore, the aim of this doctoral thesis was to develop setups for enhancing the production of membrane and secretory proteins in E. LÄS MER
