WebThe presence of gamma-TuC at microtubule ends is independent of gamma-TuRC-specific proteins and strongly correlates with the stability of microtubule ends. Strikingly, microtubule bundles lacking gamma-TuC at microtubule ends undergo extensive treadmilling in vivo, apparently induced by geometrical constraints on plus-end growth.
