细胞骨架的固有活性是其独特性质的原因,但同时也阻碍了对其的深入理解。预测其组分的特定性质在多大程度上影响整体动态特性是极具挑战性的。通过使用高密度运动分析,我们表明,只有三个组件的相互作用-分子马达,丝状肌动蛋白和交联蛋白-是足够的一个非常广泛的自组织现象。它们的范围从大规模极性结构的组装到收缩网络,并且关键地取决于交联蛋白质的特定性质。
The inherent activity of the cellular cytoskeleton is responsible for its unique properties – but at the same time impedes its thorough understanding. It is extremely challenging to predict to what extent the specific properties of its constituents affect the overall dynamic properties. By using high density motility assays, we show that the interplay of only three components – molecular motors, filamentous actin and crosslinking proteins – is sufficient for an extremely broad range of self-organization phenomena. They range from the assembly of large-scale polar structures to contracting networks and crucially depend on the specific properties of the crosslinking proteins.
