Microtubules in cilia are sufficiently stable to withstand the beating motion, but how they are stabilized while serving as tracks for intraflagellar transport and axonemal dyneins remains unknown. Here authors identify two microtubule inner proteins, FAP45 and FAP52, which stabilize the ciliary axonemes in Chlamydomonas.
