Cytoskeleton and Golgi-apparatus interactions: a two-way road of function and structure

Abstract

The Golgi apparatus is the result of a complex and dynamic interaction between a large variety of molecules that determine its architecture, protein and lipid transports, and those that integrate signals from outside and inside the cell. The cytoskeleton facilitates the functional integration of all these processes. Association and coordination between microtubules and actin filaments, as well as their respective binding and regulatory proteins, are clearly necessary for Golgi structure and function. Protein sorting, membrane fission and fusion, and the motion of Golgi-derived transport carriers are all affected by both cytoskeleton elements.
