Research Abstract

In this study, we aimed to identify enzymes that regulated tubulin polyglutamylation in primary cilia. We have finally identified three enzymes, TTLL1, TTLL6, and CCP1, as polyglutamylation-regulating enzymes in primary cilia. We found, by blocking the localization of TTLL6 into primary cilia or by the direct inhibition of TTLL6 function, that tubulin polyglutamylation was essential for maintaining the structural integrity of the ciliary axonemes. The results suggest an association of the dysregulation of tubulin polyglutamylation with a ciliary disease, Joubert syndrome. We also demonstrated that appropriate polyglutamylation level was essential for the maintenance of retinal photoreceptor cells. In addition, we found that intracellular distribution of a protein in photoreceptor cells were affected by the dysregulated hyper-polyglutamylation in CCP1-deficient mouse retina.
