The lipid bilayer surrounding any of the thin, flattened compartments that form the trans portion of the Golgi complex. [GOC:bhm, PMID:16038056, PMID:24119662]
The Golgi trans cisterna membrane is a specialized membrane compartment within the Golgi apparatus that is responsible for sorting and packaging proteins and lipids destined for secretion or delivery to other cellular compartments. It is characterized by its unique protein composition and the presence of specific enzymes involved in post-translational modifications and packaging.
The trans cisterna membrane is distinct from the cis cisterna membrane, which is located closer to the endoplasmic reticulum (ER), and the medial cisterna membrane, which lies between the cis and trans cisternae. The trans cisterna membrane is enriched in proteins involved in protein sorting, including clathrin, COPI, and COPII coat proteins. These proteins help to form vesicles that bud from the trans cisterna membrane and transport their cargo to other cellular destinations.
The trans cisterna membrane also contains a variety of enzymes involved in post-translational modifications, such as glycosylation, sulfation, and phosphorylation. These modifications can alter the function and targeting of proteins.
In addition to protein sorting and modification, the trans cisterna membrane plays a role in the formation of lysosomes. Lysosomes are organelles responsible for the degradation of cellular waste products. The trans cisterna membrane is involved in the packaging of lysosomal enzymes into vesicles that bud off and fuse with the lysosomal membrane.
The trans cisterna membrane is a dynamic structure that undergoes constant remodeling and reorganization. This allows the Golgi apparatus to adapt to changes in cellular demands and to efficiently process and transport proteins and lipids. '
