The actin cytoskeleton plays incredibly important roles in our cells.

肌动蛋白骨架在我们的细胞中扮演着至关重要的角色。

Other parts of the cytoskeleton, in this case microtubules, are responsible for long-range transportation.

细胞骨架的其它组成部分，比如说微管，则负责长途运输。

This movement is powered by one of my favorite proteins called actin, which is part of what's known as the cytoskeleton.

它的动作由我最喜欢的蛋白之一，肌动蛋白驱动，这种蛋白是所谓 “细胞骨架”的一部分。
