GRASP65 Proteins and Enzymes

GRASP65 (Golgi ReAssembly Stacking Protein) is a conserved protein that participates in the stacking of cisternae. This protein associates with GM130 and is phosphorylated by the MEK1 substrate ERK2, Polo-like kinase (Plk) and cdc2-cyclin B. GRASP65 thus plays a role in a cell cycle-dependent reorganization of the Golgi apparatus and may control mammalian cell entry into mitosis.
