1　细胞骨架概述心肌细胞骨架是一类复杂的微丝微管网状结构 ,广义的细胞骨架指维持细胞形状 ,机械抗力和形态完整的一类蛋白质 ,按结构和功能可以分为[1] :(1)肌原纤维骨架 :肌球蛋白、C -蛋白、M -蛋白等 ;(2 )真正的“细胞骨架” :微管蛋白 ,肌动蛋白 ,结蛋白等 ;(3)膜相关? 1 cytoskeleton overview Myocardial cytoskeleton is a complex microfilament microtubule network structure, the generalized cytoskeleton refers to maintain cell shape, mechanical resistance and integrity of a class of proteins, according to the structure and function can be divided into: (1) myofibril skeleton: myosin, C - protein, M - protein, etc .; (2) the real “cytoskeleton”: tubulin, actin, desmin and so on;
