The three-dimensional structure of a protein involved in the assembly of actin filaments could help to settle a long-standing scientific debate about the regulation of cytoskeletal organization. The ...
This is a preview. Log in through your library . Abstract Arp2/3 complex nucleates branched actin filaments that provide pushing forces to drive cellular processes such as lamellipodial protrusion and ...
New methods of visualizing subcortical actin filament bundles, or fibrils, in Characean internodes confirm that they are associated with chloroplasts at the surface facing the streaming endoplasm, and ...
Researchers at Kanazawa University report in eLife on deciphering the actin structure-dependent preferential cooperative binding of cofilin. The actin filament is a double-stranded helical structure ...
Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...
They play a leading role not only in muscle cells. Actin filaments are one of the most abundant proteins in all mammalian cells. The filigree structures form an important part of the cytoskeleton and ...
Actin filaments - protein structures critical to living movement from single cells to animals - have long been known to have polarity associated with their physical characteristics, with growing ...
Mitochondria have traditionally been viewed as energy-generating organelles, through oxidation of metabolic substrates and creation of a proton gradient across the inner mitochondrial membrane (IMM), ...
Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...
