Intermediate Filaments: Vimentin Moves in
Vimentin intermediate filaments move bi-directionally along microtubules in the cell. Recent work has identified the microtubule motor cytoplasmic dynein as the missing inward-directed motor that drives this movement.
متن کاملVimentin filaments regulate integrin-ligand interactions by binding to the cytoplasmic tail of integrin β3.
Vimentin, an intermediate filament protein induced during epithelial-to-mesenchymal transition, is known to regulate cell migration and invasion. However, it is still unclear how vimentin controls such behaviors. In this study, we aimed to find a new integrin regulator by investigating the H-Ras-mediated integrin suppression mechanism. Through a proteomic screen using the integrin β3 cytoplasmi...
متن کاملExpression of Keratin and Vimentin Intermediate Filaments
Rabbit bladder epithelium, grown on collagen gels and exposed to the chemical carcinogen benzo[a]pyrene, produced nontumorigenic altered foci as well as tumorigenic epithelial cell lines during 120-180d in culture. Immunofluorescence studies revealed extensive keratin filaments in both primary epithelial cells and benzo[a]pyrene-induced altered epithelial foci but showed no detectable vimentin ...
متن کاملBidirectional Interplay between Vimentin Intermediate Filaments and Contractile Actin Stress Fibers.
The actin cytoskeleton and cytoplasmic intermediate filaments contribute to cell migration and morphogenesis, but the interplay between these two central cytoskeletal elements has remained elusive. Here, we find that specific actin stress fiber structures, transverse arcs, interact with vimentin intermediate filaments and promote their retrograde flow. Consequently, myosin-II-containing arcs ar...
متن کاملEpithelial cell migration requires the interaction between the vimentin and keratin intermediate filaments
Epithelial migration plays a central role in development, wound repair and tumor metastasis, but the role of intermediate filament in this important event is unknown. We showed recently that vimentin coexists in the same cell with keratin-KRT14 at the leading edge of the migrating epidermal cells, and knockdown of vimentin impaired colony growth. Here we demonstrate that vimentin co-localizes a...
