线粒体是真核细胞中十分重要的细胞器,它密切影响着细胞能量的供应、钙离子浓度的稳态以及细胞凋亡等过程。因此,线粒体恰当的分布关乎细胞的功能和生存,这就涉及到线粒体的运动和固定。在极化细胞(如神经细胞和出芽的芽殖酵母)中,线粒体的运动与固定之间的平衡就显得更为重要。细胞骨架以及一些相关蛋白在线粒体运动过程中起着重要作用。本文对线粒体运动的要素,如骨架蛋白、马达蛋白、衔接蛋白和线粒体上的货物蛋白等进行了归纳,并对当前线粒体运动研究的进展进行了综述。
Mitochondria are elementary organelles in eukaryotic cells, which have a significant function on the cell energy supply, the calcium homeostasis, cell apoptosis, etc. Therefore, the proper mitochondria distribution, involving mitochondria movement and stationary, is linked with cell's function and survival. The balance between mitochondria movement and stationary seems more crucial in polarized cells (i.e. neuron cells) and budding yeast. The cytoskeleton and related proteins play the crucial roles in the process of mitochondrial motility, and those indispensable elements such as microtubule, microfilament, motor proteins, adaptor proteins and cargo proteins in the mitochondrion, as well as the recent studies in this field will be discussed in this review.
