The catalytic subunit of DNA polymerase δ inhibits γTuRC activity and regulates Golgi-derived microtubules

Abstract

Microtubule organization requires γ-tubulin ring complexes (γTuRCs), but the mechanisms that control γTuRC-mediated microtubule nucleation are unclear. Here the authors show that the DNA polymerase δ catalytic subunit controls noncentrosomal γTuRC activity and regulates the organization of Golgi-derived microtubules.
