The cytoskeleton consists of three types of cytosolic fibers: microtubules, microfilaments (actin filaments), and intermediate filaments. Globular tubulin subunits comprise the microtubule building block, with α/β-tubulin heterodimers forming the tubulin subunit common to all eukaryotic cells. γ-tubulin is required to nucleate polymerization of tubulin subunits to form microtubule polymers. Many cell movements are mediated by microtubule action, including the beating of cilia and flagella, cytoplasmic transport of membrane vesicles, chromosome alignment during meiosis/mitosis, and nerve-cell axon migration. These movements result from competitive microtubule polymerization and depolymerization or through the actions of microtubule motor proteins (1).

细胞骨架包括三种细胞质纤维:微管,微丝(肌动蛋白丝)和中间丝。球形微管亚基由microtubule building block组成,在所有的真核细胞中,α/β-tubulin异二聚体形成的微管亚基是很常见的。γ-tubulin对于tubulin亚基的细胞核多聚体话以形成微管复合物是必须的。许多细胞运动都是通过微管的活动介导的,包括纤毛和鞭毛的跳动,胞质膜小泡的运输、减数分裂/有丝分裂时的染色质对齐,和神经细胞轴突迁移。这些运动是微管聚合和结局的竞争结果,或者是通过微管马达蛋白的作用而发生的(1)。

The Elongator complex catalytic subunit (Elp3) acetylates α-tubulin at Lys40, while the histone deacetylase HDAC6 functions as a tubulin deacetylase. This post-translational modification may be required for dynamic cell shape remodeling, cell motility, tubulin stability, and terminal branching of cortical neurons (2,3).
