纤毛是真核生物中重要的运动、信号或感知细胞器。初级纤毛作为触角感知细胞的环境,并参与了广泛的信号通路的发展至关重要。运动纤毛驱动细胞运动或细胞周围的液体流动。这两种类型的纤毛的正常功能需要一个高度协调的双向运输系统,鞭毛内运输(IFT),这是由马达蛋白,驱动蛋白-2和IFT动力蛋白驱动。在这篇综述中,我们探讨了IFT是如何调节纤毛,重点从三个不同的角度对这个问题。首先,我们反映了运动轨迹,微管为基础的轴丝,影响IFT。其次,我们专注于马达蛋白,考虑的作用,电机的行动,合作和电机列车的相互作用发挥的调节IFT。第三,我们讨论了激酶在调节马达蛋白中的作用。我们的目标是提供机制的见解,在IFT调控纤毛,并建议未来的研究方向。
Cilia are eukaryotic organelles essential for movement, signaling or sensing. Primary cilia act as antennae to sense a cell’s environment and are involved in a wide range of signaling pathways essential for development. Motile cilia drive cell locomotion or liquid flow around the cell. Proper functioning of both types of cilia requires a highly orchestrated bi-directional transport system, intraflagellar transport (IFT), which is driven by motor proteins, kinesin-2 and IFT dynein. In this review, we explore how IFT is regulated in cilia, focusing from three different perspectives on the issue. First, we reflect on how the motor track, the microtubule-based axoneme, affects IFT. Second, we focus on the motor proteins, considering the role motor action, cooperation and motor-train interaction plays in the regulation of IFT. Third, we discuss the role of kinases in the regulation of the motor proteins. Our goal is to provide mechanistic insights in IFT regulation in cilia and to suggest directions of future research.
