Quick Summary

The cis Golgi cisternae are the initial compartment of the Golgi apparatus, a crucial organelle in eukaryotic cells. This organelle is composed of flattened, stacked membrane-bound sacs called cisternae. The Golgi apparatus receives proteins and lipids from the endoplasmic reticulum, and the cis cisternae are the first to process these molecules. Within the Golgi, these molecules undergo modifications and are sorted for transport to their final destinations within or outside the cell. The cis face membranes are generally thinner than those in other compartments of the Golgi.1

…are known generally as “cis” (cisternae nearest the endoplasmic reticulum), “medial” (central layers of cisternae), and “trans” (cisternae farthest from the endoplasmic reticulum). Two networks, the cis Golgi network and the trans Golgi network, which are made up of the outermost cisternae at the cis and trans faces, are…
