An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles. Actin filaments -- protein structures critical to living movement ...
A Novel Mechanism Promotes Actin Patch Formation to Prevent Chromatin Bridge Breakage in Cytokinesis
Chromatin bridges are strands of incompletely segregated DNA connecting the anaphase poles or daughter nuclei. If unresolved, chromatin bridges can break in cytokinesis leading to micronuclei ...
Arp2/3 complex nucleates branched actin filaments important for cellular motility and endocytosis. WASP family proteins are Arp2/3 complex activators that play multiple roles in branching nucleation, ...
The researchers experimented on a Drosophila – fruit fly – model, examining the F-actin in the brains of naturally aging animals. They compared the brains of young, middle-aged, and late-age flies and ...
University of California, San Francisco scientists have stripped the fundamental decision-making apparatus of a cell down to its bare essentials, revealing the inner workings of one of life's smallest ...
