Based on the demonstration that myosin-10 (Myo10) is important for assembly of meiotic spindles, we assessed the role of this unconventional myosin, as well as F-actin, in mitotic spindles. We find that Myo10 localizes to mitotic spindle poles and is essential for proper spindle anchoring, ...

Our results demonstrate the pivotal role of SF actomyosin contractile level on mechanical properties. In the same SF, decreasing contractile level with 10μM blebbistatin decreased stiffness, whereas increasing contractile level with 2nM calyculin A increased stiffness. Incrementally stretching and ...
Two such examples are the actin cortex, a thin contractile mesh immediately beneath the cell membrane that helps to maintain cell shape5, and stress fibers, bundles of crosslinked actin and myosin that transmit force to the extracellular matrix (ECM) through focal adhesions6. These and other F-...

肌动蛋白,肌纤蛋白:肌原纤维的蛋白质,位于Ⅰ带内与肌浆球蛋白(myosin)颗粒共同作用,可使肌肉收缩和舒张,在无盐的情况下呈球状(G-肌动蛋白),在有氯化钾和三磷酸腺苷存在时则聚合为长纤维(F-肌动蛋白)。参见actomyosin和myosin 肌动蛋白(肌纤蛋白)由两条链状分子缠绕成螺旋状的球形分子 ...
The cortex is a thin isotropic network (Figure 1(b)), which is associated with regulation of cell shape by contractile tension generated by myosin II. In addition to these types of network structures, the cell also has F-actin bundle structures (Figure 1(c)): protrusive filopodia and ...
The measurement of fluorescent-labeled actin filament movement driven by mechanoenzymes (e.g., myosin) is an important methodology for the study of molecular motors. It is assumed that the filament velocity (Vf) is analogous to the unloaded shortening velocity (Vu) seen in muscle fibers. Methods...
