The primary cilium is a microtubule‐based structure that protrudes from the cell surface in diverse eukaryotic organisms. It functions as a key signaling center that decodes a variety of mechanical and chemical stimuli and plays fundamental roles in development and homeostasis. Accordingly, structural and functional defects of the primary cilium have profound effects on the physiology of multiple organ systems including kidney, retina, and central nervous system. At the core of the primary cilium is the microtubule‐based axoneme, which supports the cilium shape and acts as the scaffold for bidirectional transport of cargoes into and out of cilium. Advances in imaging, proteomics, and structural biology have revealed new insights into the ultrastructural organization and composition of the primary cilium, the mechanisms that underlie its biogenesis and functions, and the pathologies that result from their deregulation termed ciliopathies. In this viewpoint, we first discuss the recent studies that identified the three‐dimensional native architecture of the ciliary axoneme and revealed that it is considerably different from the well‐known '9 + 0' paradigm. Moving forward, we explore emerging themes in the assembly and maintenance of the axoneme, with a focus on how microtubule‐associated proteins regulate its structure, length, and stability. This far more complex picture of the primary cilium structure and composition, as well as the recent technological advances, open up new avenues for future research.

微管相关蛋白以及与初级纤毛结构,组装,维持和拆卸的新兴联系

初级纤毛是一种基于微管的结构,在各种真核生物中都从细胞表面突出。它是一个关键的信号中心,可解码各种机械和化学刺激,并在发育和体内平衡中起基本作用。因此,初级纤毛的结构和功能缺陷对包括肾脏,视网膜和中枢神经系统在内的多器官系统的生理学具有深远的影响。初级纤毛的核心是基于微管的轴突,它支持纤毛的形状,并充当双向进出纤毛的货物的支架。影像学,蛋白质组学和结构生物学的进步揭示了对初级纤毛的超微结构和组成的新见解,其生物发生和功能的基础机理,以及因其失调而引起的病理学称为纤毛病。用这种观点,我们首先讨论最近的研究,这些研究确定了睫状轴突的三维三维结构,并揭示了它与众所周知的“ 9 + 0”范式有很大不同。展望未来,我们探索轴蛋白的组装和维护中的新兴主题,重点关注微管相关蛋白如何调节其结构,长度和稳定性。有关纤毛主要结构和组成的复杂得多的图景,以及最近的技术进步,为将来的研究开辟了新途径。我们首先讨论最近的研究,这些研究确定了睫状轴突的三维三维结构,并揭示了它与众所周知的“ 9 + 0”范式有很大不同。展望未来,我们探索轴蛋白的组装和维护中的新兴主题,重点关注微管相关蛋白如何调节其结构,长度和稳定性。有关纤毛主要结构和组成的复杂得多的图景,以及最近的技术进步,为将来的研究开辟了新途径。我们首先讨论最近的研究,这些研究确定了睫状轴突的三维三维结构,并揭示了它与众所周知的“ 9 + 0”范式有很大不同。展望未来,我们探索轴蛋白的组装和维护中的新兴主题,重点关注微管相关蛋白如何调节其结构,长度和稳定性。纤毛主要结构和组成的复杂得多的图景,以及最近的技术进步,为将来的研究开辟了新途径。着重研究微管相关蛋白如何调节其结构,长度和稳定性。纤毛主要结构和组成的复杂得多的图景,以及最近的技术进步,为将来的研究开辟了新途径。着重研究微管相关蛋白如何调节其结构,长度和稳定性。有关纤毛主要结构和组成的复杂得多的图景,以及最近的技术进步,为将来的研究开辟了新途径。
