Molecular basis for Golgi maintenance and biogenesis.
The Golgi apparatus contains thousands of different types of integral and peripheral membrane proteins, perhaps more than any other intracellular organelle. To understand these proteins' roles in Golgi function and in broader cellular processes, it is useful to categorize them according to their contribution to Golgi creation and maintenance. This is because all of the Golgi's functions derive from its ability to maintain steady-state pools of particular proteins and lipids, which in turn relies on the Golgi's dynamic character - that is, its ongoing state of transformation and outgrowth from the endoplasmic reticulum. Here, we categorize the expanding list of Golgi-associated proteins on the basis of their role in Golgi reformation after the Golgi has been disassembled. Information gained on how different proteins participate in this process can provide important insights for understanding the Golgi's global functions within cells.
