细胞骨架是以聚合蛋白为基础的自组织网络:肌动蛋白、微管蛋白,并由运动蛋白驱动,如肌球蛋白、动蛋白和动力蛋白。它们积极的达尔文进化使它们能够接近优化的功能(自组织临界性)。细胞骨架运动蛋白myosin-1在真核进化过程中的主要特征与肌动蛋白和微管蛋白相似,但在动力学功能方面也有显著差异。优化(长)水病理波表征分子水平达尔文进化向优化功能(自组织临界)。myosin-1的N端结构域和中央结构域在真核生物中以不同的速度进化,其中中央结构域的水病理极值在人类中最活跃。测试表明,水病理缩放可以产生优于1%的精确度,接近优化的功能。向同步水平极值的进化与Mys-1在人类中涉及高尔基复合体的特殊功能有关。

英文摘要:
Cytoskeletons are self-organized networks based on polymerized proteins: actin, tubulin, and driven by motor proteins, such as myosin, kinesin and dynein. Their positive Darwinian evolution enables them to approach optimized functionality (self-organized criticality). The principal features of the eukaryotic evolution of the cytoskeleton motor protein myosin-1 parallel those of actin and tubulin, but also show striking differences connected to its dynamical function. Optimized (long) hydropathic waves characterize the molecular level Darwinian evolution towards optimized functionality (self-organized criticality). The N-terminal and central domains of myosin-1 have evolved in eukaryotes at different rates, with the central domain hydropathic extrema being optimally active in humans. A test shows that hydropathic scaling can yield accuracies of better than 1% near optimized functionality. Evolution towards synchronized level extrema is connected to a special function of Mys-1 in humans involving Golgi complexes.
