Summary
Mass spectrometry reveals how the endoplasmic reticulum (ER) maintains protein homeostasis. This technology helps understand ER protein quality control, stress responses, and disease-related changes.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- The endoplasmic reticulum (ER) is crucial for protein homeostasis (proteostasis), processing a significant portion of the human proteome.
- Dysregulation of ER proteostasis is linked to various diseases, necessitating research into its quality control mechanisms.
- Protein quality control involves dynamic protein-protein interactions with chaperones and other factors within the ER.
Purpose of the Study:
- To highlight recent advances in mass spectrometry for investigating ER protein quality control.
- To elucidate the topological arrangement of the proteostasis network.
- To understand stress response mechanisms and disease-specific alterations in proteostasis.
Main Methods:
- Mass spectrometry-based investigations of ER protein-protein interactions.
- Characterization of the proteostasis network's structure and dynamics.
- Analysis of stress-induced changes in ER protein quality control.
Main Results:
- Mass spectrometry has revealed the topological organization of the ER proteostasis network.
- Insights into stress response pathways that modulate ER proteostasis capacity have been gained.
- Disease-specific alterations in proteostasis network engagement have been identified.
Conclusions:
- Mass spectrometry is a powerful tool for understanding ER protein quality control mechanisms.
- Further research using mass spectrometry can uncover new regulatory processes in ER proteostasis.
- This technology holds promise for advancing our understanding of diseases linked to ER dysfunction.

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

02:26Protein Networks
4.3K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

02:04Protein-protein Interfaces
14.2K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

01:32Export of Misfolded Proteins out of the ER
4.7K
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...

01:37The Unfolded Protein Response
5.9K
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

01:26Protein Modifications in the RER
6.3K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...
