Bio/Research
The Golgi complex is the “Grand Central Station” within our cells, serving as the primary sorting organelle at the nexus of the secretory and endocytic trafficking pathways. For example, virtually all proteins that eukaryotic cells display on their surface at the plasma membrane are first synthesized at the endoplasmic reticulum and then trafficked to the Golgi complex. Once at the Golgi, proteins find themselves at a crossroads: they may be trafficked to the plasma membrane, to endocytic organelles, to lysosomal organelles, back to the endoplasmic reticulum, or they may remain within the Golgi complex. We view the Golgi as an excellent model for investigating how decisions are made at the level of an organelle: How does the Golgi maintain homeostasis in the face of constant flux? How does the Golgi respond to changes in cargo load? Does the Golgi communicate with other organelles?
