  1. 1. Cross-linked Profilin:actin - A tool to study actin dynamics in non-muscle cells

    Författare :Staffan Grenklo; Roger Karlsson; Dan Lindholm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actin dynamics; profilin; actin; Profilin-actin complex; Cell motility; synaptic vesicle trafficing; Far western; fluorescence microscopy; Cell biology; Cellbiologi;

    Sammanfattning : The microfilament system, consisting of actin and a number of auxiliary proteins, is fundamental for cell motility. Its dynamic organization depends on receptor-mediated signals, leading to rapid polymerizations and depolymerizations of actin. LÄS MER

  3. 2. Profilin:actin in cell motility : A search for profilin:actin binding proteins

    Författare :Thomas Johansson; Roger Karlsson; Björn Öbrink; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; profilin; actin; Cell biology; Cellbiologi;

    Sammanfattning : The profilin:actin complex is a major source of actin for actin filament growth in vivo. A number of proteins regulating either profilin or actin has been described since profilin:actin was isolated during the 1970s. Since then, profilin and actin and their binding partners have been intensively studied. LÄS MER

  4. 3. The molecular dynamics of actin : role of nucleotide, divalent cation, and actin binding proteins for the interdomain relationship in actin

    Författare :Herwig Schüler; Joel Vandekerckhove; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Cell Biology; zoologisk cellbiologi;

  5. 4. Biophysical studies of the actin-myosin motor system and applications in nanoscience

    Författare :Mohammad A. Rahman; Alf Månsson; Kazuhiro Oiwa; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; myosin II; actin; actomyosin force generating cycle; blebbistatin; in vitro motility assay; actin affinity purification; blocking actin; bionanodevices; proteinase k; SDS; triton X100; surface recycling; engineered myosin motor; programmable gate; biocomputation.; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : The actin-myosin motor system plays important roles in cellular processes. In addition, actin and myosin have been used for developments towards nanotechnological applications in recent years. LÄS MER

  7. 5. The Actin Filament System : Its Involvement in Cell Migration and Neurotransmitter Release

    Författare :Anna-Karin Johnsson; Roger Karlsson; Stéphane Gasman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Actin; Profilin; Synaptotagmin; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Sammanfattning : The microfilament system consists of actin filaments as the major component and is regulated by a number of actin binding proteins. It is juxtaposed to the plasma membrane where it forms a dense cortical weave from where it pervades into the cell interior. LÄS MER
