Chlamydomonas reinhardtii has two apically localized flagella that are maintained at an equal and appropriate length. Assembly and maintenance of flagella requires a microtubule-based transport system known as intraflagellar transport (IFT). During IFT, proteins destined for incorporation into or removal from a flagellum are carried along doublet microtubules via IFT particles. Regulation of IFT activity therefore is pivotal in determining the length of a flagellum. Reviewed is our current understanding of the role of IFT and signal transduction pathways in the regulation of flagellar length.
莱茵衣藻有两条位于顶端的鞭毛,它们保持着相等且合适的长度。鞭毛的组装和维持需要一种基于微管的运输系统,即鞭毛内运输(IFT)。在IFT过程中, destined for incorporation into or removal from a flagellum的蛋白质通过IFT颗粒沿着双联微管运输。因此,IFT活性的调节对于确定鞭毛的长度至关重要。本文综述了我们目前对IFT和信号转导途径在鞭毛长度调节中的作用的理解。
原文中“destined for incorporation into or removal from a flagellum”表述不太完整准确,可能影响对整体内容的理解,但按照要求未做修改。
