| Mitotic phosphorylation of the peripheral Golgi protein Nir 2 by Cdk 1 provides a docking mechanism for Plk 1 and affects cytokinesis completion . ^^^ Here we show that , at the onset of mitosis , Cdk 1 phosphorylates the peripheral Golgi protein Nir 2 at multiple sites ; of these , S 382 is the most prominent . ^^^ Phosphorylation of Nir 2 by Cdk 1 facilitates its dissociation from the Golgi apparatus , and phospho Nir 2 ( pS 382 ) is localized in the cleavage furrow and midbody during cytokinesis . ^^^ |
