Myomegalin is necessary for the sufficient growth of microtubules from the centrosomes. The CM-MMG isoform binds at the centrosome with γ-tubulin in an AKAP9-dependent manner and on the near side of the Golgi apparatus, while the EB-MMG isoform binds with MAPRE1 at the Golgi apparatus and increases MAPRE1's effects on microtubule growth.
