The disassembly, reassembly and stability of CCMV protein capsids.
Efficient procedures are described for the disassembly of Cowpea Chlorotic Mottle Virus (CCMV) into its viral-RNA and capsid-protein components, the separation of the RNA and protein, and the reassembly of the purified protein into higher order nanoscale structures. These straightforward biochemical techniques result in high yield quantities of protein suitable for further biophysical studies (...
متن کاملPhosphorylation and disassembly of intermediate filaments in mitotic cells.
As baby hamster kidney (BHK-21) cells enter mitosis, networks of intermediate filaments (IFs) are transformed into cytoplasmic aggregates of protofilaments. Coincident with this morphological change, the phosphate content of vimentin increases from 0.3 mol of Pi per mol of protein in interphase to 1.9 mol of Pi per mol of protein in mitosis. A similar increase in phosphate content is observed w...
متن کاملCellular Motility Driven by Assembly and Disassembly of Actin Filaments
Motile cells extend a leading edge by assembling a branched network of actin filaments that produces physical force as the polymers grow beneath the plasma membrane. A core set of proteins including actin, Arp2/3 complex, profilin, capping protein, and ADF/cofilin can reconstitute the process in vitro, and mathematical models of the constituent reactions predict the rate of motion. Signaling pa...
متن کاملCDK1 and PLK1 coordinate the disassembly and reassembly of the nuclear envelope in vertebrate mitosis
Micronuclei (MN) arise from chromosomes or fragments that fail to be incorporated into the primary nucleus after cell division. These structures are a major source of genetic instability caused by DNA repair and replication defects coupled to aberrant Nuclear Envelope (NE). These problems ultimately lead to a spectrum of chromosome rearrangements called chromothripsis, a phenomenon that is a ha...
متن کاملSaccharomyces cerevisiae vacuolar H+-ATPase regulation by disassembly and reassembly: one structure and multiple signals.
Vacuolar H(+)-ATPases (V-ATPases) are highly conserved ATP-driven proton pumps responsible for acidification of intracellular compartments. V-ATPase proton transport energizes secondary transport systems and is essential for lysosomal/vacuolar and endosomal functions. These dynamic molecular motors are composed of multiple subunits regulated in part by reversible disassembly, which reversibly i...
