  2. 6. NMR studies on calcium-induced conformational transitions in calmodulin

    Author : Johan Evenäs; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; NMR; conformational exchange; calmodulin; calcium binding; Fysikalisk kemi;

    Abstract : Nuclear magnetic resonance (NMR) spectroscopy was used in order to investigate the relationships between structure, dynamics and calcium binding in the intracellular regulatory protein, calmodulin. Calmodulin consists of two similar domains, each binding two calcium ions with positive cooperativity. READ MORE

  4. 7. Motility of human polymorphonuclear leukocytes : An image processing approach

    Author : Mikael Gustafsson; Erik Gylfe; Linköpings universitet; []
    Keywords : Human polymorphonuclear leukocytes; locomotion; phagocytosis; Saccharomyces cerevisiae; membrane transport; intracellular free calcium; cellular pH; water influx; actin dynamics; digital video microscopy; image processing; fura-2; BCECF; DII; MEDICINE; MEDICIN;

    Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE

  5. 8. The megalin receptor

    Author : Göran Hjälm; Uppsala universitet; []

    Abstract : Ionized calcium is a major player in the living organism. Its importance in both intra- and extracellular mechanisms have been studied in a broad number of publications. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 10. The role of calcium and calcium-regulated proteins in neutrophil phagocytosis

    Author : Petra Jerström Skarman; Urban Gullberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Neutrophil phagocytosis is an essential component of the innate immunity against invading pathogens. The two types of phagocytosis that are investigated in detail are IgG- and C3bi-mediated phagocytosis. Although the two types are controlled differently, they share the same driving force - reorganisation of the actin cytoskeleton. READ MORE
