Five proteins in Drosophila (DGT2 through DGT6) have been identified that are necessary and responsible for facilitating the localization of γ-tubulin to existing MTs and are not associated with its localization at the centrosome.
The identification of five proteins in Drosophila (DGT2 through DGT6) has revealed their critical function in positioning γ-tubulin on existing microtubule filaments, separate from their association with the centrosomal region.
