骨骼肌纤维是极端结构和功能特化的终点,但其薄和厚细丝的基本成分,肌动蛋白和肌球蛋白,与非骨骼肌细胞中运动系统的成分相似。肌动球蛋白系统的各种调节和锚定蛋白也是如此。低等真核生物细胞骨架蛋白的序列信息表明,在进化过程中已经出现了与肌肉相关的蛋白质。这些蛋白质共同构成了各种生物体非肌肉细胞中基于肌动蛋白的马达。通常这些蛋白质是由结构域构建的:具有确定结构和功能的单元,可以用作模块来生成相关蛋白质家族。分子遗传学家提出了三个主要问题:(a)细胞骨架蛋白质中结构域的作用是什么,(B)一级序列和功能之间的关系是什么,(c)这些蛋白质的体内活性是什么?在这篇综述中,我们涵盖了肌动蛋白,肌球蛋白,和蛋白质,调节这两种蛋白质的活性或组装状态,但我们不讨论系统的蛋白质,如黏着斑蛋白和血影蛋白的细胞骨架的质膜锚。我们总结了遗传学方法
Skeletal muscle fibers are endpoints of extreme structural and functional specialization, but the basic components of their thin and thick filaments, actin and myosin, are similar to the constituents of motor systems in non­ muscle cells. The same is true for various regulatory and anchoring proteins of the actomyosin system. Sequence information of cytoske1etal proteins from lower eukaryotes indicates that proteins related to those in muscles have emerged during evolution. Together these proteins constitute the actin-based motors in non-muscle cells of a great variety of organisms. Often these proteins are built of domains: units of defined structure and function that can be used as modules to generate families of related proteins. Three principal questions are posed by molecular geneticists: (a) what is the role of domains in cytoskeletal proteins, (b) what is the relationship between primary sequence and function, and (c) what are the in vivo activities of these proteins? In this review we cover actin, myosin, and proteins that reg­ ulate the activity or assembly state of these two proteins, but we do not discuss the system of proteins like vinculin and spectrin that anchor the cytoskeleton to the plasma membrane. We summarize genetic approaches
