actin

The toxin caused the actin filaments in the fish cells to collapse.

Tropomyosins combine with the protein, actin, to form actin filaments, making up part of the cell's cytoskeleton.

Rac, Rho and Cdc42 are the three best-characterized members of the Rho family (Etienne-Manneville and Hall, 2002), which can interact with and activate downstream effectors to control the assembly of actin filaments and their organization into complex structures (Bishop and Hall, 2000).

Cell nuclei and actin filaments were stained according to the methods of Yoon et al.

Actin filaments may play a vital role in compartmentation and substrate channeling in glycolysis (1).

They found that SS2 caused actin filaments to clump together--or bundle--which stopped plant cells from dividing.

Thickening of the actin filaments at the cell edge provided the bending force to extrude the virus particles.

Actin filaments are fine threads composed of multiple subunits--polymers that line up like a string of pop beads--which give structure to the cell, as well as drive shape changes, cell movements, and other cellular processes.

Dystrophin binds to subplasmalemmal actin filaments via its amino-terminal domain.

Using actin-specific rhodamine phalloidin as a fluorescent marker, 5-HT-treated cells were found to have fewer actin filaments at the cell periphery, increased stress fiber formation, and smoother, denser edges than control cells.

Additionally, living isolated pharynxes were treated with dihydrocytochalasin B, a compound known to disrupt actin filaments.

Two hypotheses will be tested: either MyoIIA induces phase separation in membrane tubes by the formation of actomyosin patches, which then leads to fission; or MyoIIA contracts short actin filaments around the membrane tubes in a manner similar to its role during the formation of the cleavage furrow in cytokinesis.

David Williams, who earned his doctorate at the UW while conducting the research, said that the predominant thinking of the last 50 years is that 100 percent of the muscle force comes from changes as muscles shorten and myosin and actin filaments overlap.

To address this growing need, GeneTex has developed a new line of subcellular and organelle marker antibodies that are highly specific to ribosomes, centrosomes, mitochondria (inner and outer membrane), the endoplasmic reticulum, the Golgi apparatus, kinetochores, lysosomes, microtubules/spindles, actin filaments, Cajal bodies, the nuclear envelope, the nucleolus and the nucleus.
