Abstract

Cytoplasmic dynein is a microtubule-based motor protein that transports membranes in cells. The movement driven by a single dynein molecule in vitro is not as robust as dynein-driven movements in cells. A new study suggests that transport by multiple dyneins is more similar to cellular motions.

摘要

细胞质动力蛋白是一种基于微管的驱动蛋白，在细胞中负责运输膜结构。在体外，单个动力蛋白分子驱动的运动不如在细胞中由动力蛋白驱动的运动强劲。一项新的研究表明，多个动力蛋白的运输更类似于细胞运动。
