The proposed mechanism for breakage of the actomyosin cortex may be used for cell polarization. |
|
One such polymer, polyethylene glycol, molecular weight 4000, has been used to potentiate the actomyosin interaction in solution. |
|
Originally, this force was attributed to an actomyosin system similar to muscle. |
|
We have a worm whose body wall is a collagenous membrane and whose engine is the muscle protein actomyosin. |
|
We presented evidence implicating actin polymerization and not actomyosin activity as the dominant mechanism actuating the stiffening response. |
|
The lower slope could indicate a stronger actomyosin bond in the slower muscle. |
|
This behavior is consistent with the idea that a small amount of rigorlike, stereospecific actomyosin complexes are formed as a result of normal contractile activity. |
|
It has been recognized that various NTPs have different affinities for actomyosin, and myosins complexed with these NTPs or their products have different affinities for actin. |
|
For example, changes in the shape of cells or cell fragments in which the microtubules are destroyed, we have observed, are based on dynamic rearrangements of the actomyosin cortex. |
|
The authors reported that the actomyosin complex is pulled in the direction of meromyosin fraction of the main myosin helix. |
|
For example, preliminary studies correlating contractile ring dynamics with cell shape change indicate that actomyosin organization, not just quantity, affects the kinetics of cell shape transitions. |
|
We study the molecular mechanisms of cell shape change in cytokinesis: the assembly, organization and function of the actomyosin contractile ring. |
|
On the other hand, phosphates increase the ionic strength in the meat and improve the condition of the cold meat by breaking up the actomyosin complexes. |
|
This results in a transient actin network, that naturally accommodates intranetwork flows of the actomyosin dense regions as a consequence of filament unbinding and rebinding. |
|
Fusion events in vivo, particularly in embryonic development, often involve the purse-string contraction of a pluricellular actomyosin cable at the free edge. |
|
This process is accomplished through the assembly and constriction of a contractile ring, a complex actomyosin network that remains poorly understood on the molecular level. |
|
The scientists were also able to identify the protein components responsible for moving the nuclear piston, including actomyosin, vimentin and nesprin. |
