  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. 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

  4. 3. 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

  5. 4. The dynamic microfilament system : cellular organization of actin and profilin and their association with cell signalling

    Författare :Lucie Hájková; Karl-Eric Magnusson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : Active shape changes and movement of whole cells, and translocations within cells are essential to life. For instance, during embryogenesis cell migration is a central theme. Wound healing depends on increased and directed motile activity of several cell types. LÄS MER

  7. 5. Cbl in Regulation of Growth Factor Receptor Endocytosis and Actin Dynamics

    Författare :Iwona Szymkiewicz; Ivan Dikic; Silvia Giordano; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; RTK; Cbl; endocytosis; ubiquitination; actin; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Proteins belonging to the Cbl family are multidomain scaffolds that participate in numerous processes, assembling signaling complexes and mediating attachment of ubiquitin to receptor and non-receptor tyrosine kinases.We characterized a novel role for Cbl and Cbl-b in ligand-dependent internalization of growth factor receptors.
