The mesh hypothesis of Golgi dynamics

Christoph Lorra & Wieland B. Huttner

The GTP-binding protein ARF induces the recruitment to the Golgi membrane of kinases that catalyse the synthesis of the lipid phosphatidylinositol-4,5-bisphosphate. This lipid acts as a binding site for certain actin-binding proteins, which may change the Golgi membrane skeleton to a form that allows membrane traffic.
