| Research Abstract |
The outer doublet microtubules in ciliary and flagellar axonemes are connected with each other by elastic links called the interdoublet (nexin) links. This structures are important for maintenance of axonemal structure and converting sliding between doublets into bending. The link has been found in early electron microscopic studies, but little is known about its molecular composition. In this study I cloned putative nexin components from partially extracted axonemes, in which outer doublets remained connected together. Localization and mutational analyses confirmed the involvement of these components in the nexin links.
