Cytoskeleton dynamics
Four of six talks in the Cytoskeleton Dynamics Minisymposium described work on filament end-binding proteins: a reflection of the central role they play in cytoskeletal organization. Scott Hansen's single-molecule study of purified vasodilator-stimulated phosphoprotein (VASP) demonstrated that it is a weakly processive actin polymerase that is targeted to filament ends by actin monomers. Hansen...
متن کاملCytoskeleton dynamics in axon regeneration
Recent years have seen cytoskeleton dynamics emerging as a key player in axon regeneration. The cytoskeleton, in particular microtubules and actin, ensures the growth of neuronal processes and maintains the singular, highly polarized shape of neurons. Following injury, adult central axons are tipped by a dystrophic structure, the retraction bulb, which prevents their regeneration. Abnormal cyto...
متن کاملCytoskeleton Dynamics: Mind the Gap!
A new study presents a quantitative biophysical model of microtubule aster growth with autocatalytic microtubule nucleation. The model accounts for asters that grow indefinitely, even when their microtubules are unstable.
متن کاملFast and slow dynamics of the cytoskeleton.
Material moduli of the cytoskeleton (CSK) influence a wide range of cell functions. There is substantial evidence from reconstituted F-actin gels that a regime exists in which the moduli scale with frequency with a universal exponent of 3/4. Such behaviour is entropic in origin and is attributable to fluctuations in semiflexible polymers driven by thermal forces, but it is not obvious a priori ...
متن کاملMeeting report - Cellular dynamics: membrane-cytoskeleton interface.
The first ever 'Cellular Dynamics' meeting on the membrane-cytoskeleton interface took place in Southbridge, MA on May 21-24, 2017 and was co-organized by Michael Way, Elizabeth Chen, Margaret Gardel and Jennifer Lippincott-Schwarz. Investigators from around the world studying a broad range of related topics shared their insights into the function and regulation of the cytoskeleton and membrane...
