GP73 and liver disease: a (Golgi) complex enigma
The American Journal of Gastroenterology
|June 8, 2004
Summary
GP73 protein is overexpressed in various liver diseases, potentially originating from activated stellate cells. While not useful for diagnosis, GP73 may serve as a general marker for liver disease progression and injury.
Area of Science:
- Cell Biology
- Hepatology
- Protein Biochemistry
Background:
- The Golgi apparatus is crucial for protein modification and cellular sorting.
- Many resident membrane proteins, including GP73, have poorly understood functions.
- GP73 protein is implicated in various cellular processes.
Purpose of the Study:
- To investigate the expression and potential source of GP73 protein in liver diseases.
- To evaluate the diagnostic utility of GP73 in liver conditions.
Main Methods:
- Analysis of GP73 protein expression in liver tissues.
- Investigation of potential cellular sources of GP73, including stellate cells.
Main Results:
- GP73 protein is overexpressed in diverse acute and chronic liver diseases.
- GP73 expression was observed in sinusoidal lining cells.
- Activated stellate cells are suggested as a potential source of GP73.
Conclusions:
- GP73 is a widespread marker in liver disease but may lack specificity for etiological diagnosis or staging.
- Further research into GP73's role could illuminate liver injury pathogenesis.
- GP73 may serve as a general indicator of liver disease status.

Vesicular Tubular Clusters
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

Golgi Matrix Proteins
Golgi matrix proteins are a group of highly dynamic proteins that maintain the stacked structure of Golgi. These proteins adapt to rapid morphological changes of the Golgi during the cell cycle. During cell division, mild proteolysis removes these connections resulting in Golgi unstacking. In The daughter cells, these proteins help reassemble the unstacked Golgi.
One of the first identified Golgi matrix proteins was GM130, a rod-like protein located in the cis-Golgi. Subsequently, many Golgi...

Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
GPI Anchoring of Proteins in the ER Membrane
GPI-anchoring is a post-translational, reversible protein modification that is ubiquitous in eukaryotes. Such proteins are primarily present on the exoplasmic leaflet of the plasma membrane.
GPI-anchor structure
A sequence of 11 enzymatic reactions results in the synthesis of the complete GPI anchor consisting of a hydrophobic and a hydrophilic portion. The hydrophobic portion comprises phosphatidylinositol, while the hydrophilic part comprises polar groups like phosphoethanolamine,...

Export of Misfolded Proteins out of the ER
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
Transport Across the Golgi
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
