36) Furthermore, the myosin head could consistently interact with actin without moving away from the actin filament
because it was firmly affixed to a large scanning probe thus preventing diffusion.
The whole system thus returns to the rest state with the active troponin I and myosin ATPase by blocking active sites on actin filament
sup] As a protein that affects the dynamics of the actin cytoskeleton via stabilization of actin filaments
, transgelin is both directly and indirectly involved in many processes such as migration, proliferation, differentiation, and apoptosis.
Palladin is a regulator of actin filament
bundles at the ectoplasmic specialization in adult rat testes," Endocrinology 154(5): 1907-1920.
The fission yeast cytokinesis formin Cdc12p is a barbed end actin filament
capping protein gated by profilin.
Polymerization and organization of actin filaments
One likely candidate for the observed magnetic ordering along an ATP-activated actin filament
may be a quantum entanglement.
Electron microscopic determination of the actin filament
end at which cytochalasin B blocks monomer addition using the acrosomal actin bundle from horseshoe crab sperm.
labeled with rhodamine--phalloidin were allowed to move on Physarum or scallop myosin fixed to a nitro cellulose-coated glass surface.
Morphogenetic movements include gastrulation, convergent extension of notochord cells, and neurulation, and these morphogenetic movements share two features: the actin filament
has important roles and the small GTPase Rho mediates F-actin formation.
Cells treated for 24 hr with 10-6 M FL (Figure 2B), however, contained no visible stress fibers, but rather exhibited shortened and disorganized actin filaments
Here we will focus on how the underlying actin filament
bundle regulates filopodium growth and retraction cycles at the micrometer and seconds scales.
6) A tropomyosin molecule is thought to be a canonical coiled-coil protein, about 40 nm in length, which binds to actin filament
covering seven contiguous actin protomers (monomers), (7) with the length of an actin protomer being about 5.
In the Characean cell, cortical fibrils were confirmed to be composed of actin filament
bundles by observation of the arrowhead structure formed by binding with skeletal muscle heavy meromyosin.
Purification and characterization of caldesmon 77: a calmodulin-binding protein that interacts with actin filament
from bovine adrenal medulla.
