Force transduction by Triton cytoskeletons
Force-initiated signal transduction can occur either via membrane-based ionic mechanisms or through changes in cytoskeletal-matrix linkages. We report here the stretch-dependent binding of cytoplasmic proteins to Triton X-100 cytoskeletons of L-929 cells grown on collagen-coated silicone. Triton X-100-insoluble cytoskeletons were stretched by 10% and incubated with biotinylated cytoplasmic prot...
متن کاملCytoskeletons by the sea.
The ESF-EMBO meeting, 'Emergent Properties of the Cytoskeleton: Molecules to Cells', took place in October 2010 in San Feliu dex Guíxols on the eastern coast of Spain. It brought together a diverse group of international cytoskeletal researchers who gave presentations on topics from structural biology and biophysical analyses of the cytoskeleton and its motors, to studies of the role of cytoske...
متن کاملForce transduction by the microtubule-bound Dam1 ring.
The coupling between the depolymerization of microtubules (MTs) and the motion of the Dam1 ring complex is now thought to play an important role in the generation of forces during mitosis. Our current understanding of this motion is based on a number of detailed computational models. Although these models realize possible mechanisms for force transduction, they can be extended by variation of a...
متن کاملCdc42 controls the polarity of the actin and microtubule cytoskeletons through two distinct signal transduction pathways.
Cdc42, a Rho family GTPase, is a key regulator of cell polarity. In Saccharomyces cerevisiae, it is required for polarized bud formation and pheromone gradient sensing, while in higher eukaryotes, it participates in asymmetric cell division, directional sensing during migration, and morphogenesis. Using a scratch-induced fibroblast migration assay, we previously showed that Cdc42 controls the p...
متن کاملNeuronal and glial cytoskeletons.
Long-awaited evidence for in vivo functions of the major neuronal microtubule associated proteins indicates that they are directly involved in neurite extension. Companion evidence reveals an intrinsic role for glial intermediate filaments in glial cell extension along neurites and for neurofilaments in establishing axonal caliber. New fluorescence and photoactivation experiments require a re-t...
