  1. 16. Calreticulins- Calcium-Binding Proteins with Functional Diversity and Evolutionary Duality

    Författare :Staffan Persson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; plant; isoforms; evolution; diversity; differential regulation; chaperone; calnexin; calmegin; calcium; Arabidopsis; calreticulin; Växtbiokemi;

    Sammanfattning : Calreticulin is a multifunctional protein mainly localized in the endoplasmic reticulum in eukaryotic organisms, except yeasts. The protein comprises three distinct regions: the N-terminal N domain, the C-terminal C domain, and the central P domain, reflecting the functional diversity of calreticulin. LÄS MER

  3. 17. Interaction of Calcium Ions with Lipid Membranes

    Författare :Baharan Ali Doosti; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Sammanfattning : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  4. 18. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

    Författare :Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; rat; chicken; parathyroid gland; stomach; vitamin D; PTH; CT; calciotropic hormones; Gastrin; calcium; ECL cell; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. LÄS MER

  5. 19. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

    Författare :Juha Saarikettu; Thomas Grundström; Dan Holmberg; Mikael Sigvardsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. LÄS MER

  7. 20. Calcium-dependent Affinity Domains for the Purification of Antibodies and Antibody Fragments

    Författare :Julia Scheffel; Sophia Hober; Alois Jungbauer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibodies; Antibody fragments; Biomanufacturing; Protein purification; Protein engineering; Protein A; ZCa; Calcium; Mild elution; Bioteknologi; Biotechnology;

    Sammanfattning : Antibodies are essential proteins in both our bodies and biotechnological research, and hold outstanding therapeutic value. The market for antibody-based therapeutics has grown exponentially during the last decades, owing to several advantages over small molecule drugs, such as fewer undesirable side effects associated with a higher target specificity.
