Quick Summary

The trans Golgi cisternae are part of the Golgi apparatus, a vital organelle in eukaryotic cells. The Golgi apparatus functions to modify, sort, and package proteins and lipids for transport within or out of the cell. It is composed of flattened, stacked pouches called cisternae, typically arranged into cis, medial, and trans compartments. The trans Golgi network, formed by the outermost cisternae at the trans face, is crucial for sorting molecules before they are released in vesicles to their final destinations. This process ensures that proteins and lipids reach their correct locations, whether it's the cell membrane, other organelles, or secretion outside the cell.12
