人体内几乎所有的细胞都含有细胞骨架系统。细胞骨架系统及其相关的蛋白质可能数以千计,但目前人们对其中的大多数蛋白质还所知甚少。对构成细胞质中纤维状网络支架的结构和功能,人们已经有了基本的了解,它的主要成分有三类,即直径6nm的微丝,直径25nm的微管和界于两者之间的中间丝(直径8～12nm)。一般认为中间丝在维持细胞的完整性,细胞的形状和细胞器在胞质中的定位,以及细胞位移中发挥作用。中间丝蛋白在各类细胞呈特征性的表
Almost all cells in the human body contain a cytoskeletal system. There may be thousands of cytoskeletal systems and their associated proteins, but little is known about most of these proteins. There is already a basic understanding of the structure and function of the fibrous network scaffold that constitutes the cytoplasm. Its main components are three types: microfilaments with a diameter of 6 nm, microtubules with a diameter of 25 nm, and intermediate wires between the two. (8 to 12 nm in diameter). It is generally believed that the intermediate filament plays a role in maintaining the integrity of the cell, the shape of the cell and the location of the organelle in the cytoplasm, as well as the cell shift. The appearance of intermediate silk proteins in various types of cells
