 The Golgi apparatus, which participates in glycosylation and transport of proteins and lipids in the secretory pathway, consists of a series of stacked cisternae (flattened membrane sacs).Interactions between the Golgi and microtubules are thought to be important for the reorganization of the Golgi after it fragments during mitosis.The golgins are a family of proteins, of which the protein encoded by this gene is a member, that are localized to the Golgi.
