Abstract

In yeast and animal cells, the sterol composition of membranes is a key factor that controls the polarity of membrane proteins by regulating their intracellular trafficking or lateral diffusion. A recent study in Nature Cell Biology demonstrates that plant sterols play a major role in the acquisition of cell polarity by modulating endocytosis after cell division.

摘要

在酵母和动物细胞中，膜的甾醇组成是一个关键因素，它通过调节膜蛋白的细胞内运输或侧向扩散来控制膜蛋白的极性。《自然·细胞生物学》最近的一项研究表明，植物甾醇在细胞分裂后通过调节内吞作用在细胞极性的获得中起主要作用。
