Summary
Maintaining proteome integrity is vital for cell survival. This review explores plant endoplasmic reticulum (ER) protein quality control, including the unfolded protein response (UPR), ER-associated degradation (ERAD), and ER-phagy, and their interactions.
Area of Science:
- Plant cell biology
- Molecular biology
- Biochemistry
Background:
- Proteome integrity is crucial for cellular function and survival.
- The endoplasmic reticulum (ER) synthesizes secretory and membrane proteins.
- Misfolded proteins in the ER cause stress, compromising cellular functions.
Purpose of the Study:
- To review recent advances in ER protein homeostasis mechanisms in plants.
- To discuss the crosstalk between different ER protein quality control systems.
- To identify unanswered questions in the field of plant ER protein homeostasis.
Main Methods:
- Literature review of recent research on ER protein quality control in plants.
- Analysis of mechanisms including the unfolded protein response (UPR).
- Examination of ER-associated degradation (ERAD) and ER-phagy pathways.
Main Results:
- Plants utilize sophisticated, conserved systems for ER protein quality control.
- The unfolded protein response (UPR), ERAD, and ER-phagy are key mechanisms.
- Crosstalk exists between these quality control systems.
Conclusions:
- Understanding plant ER protein homeostasis is essential for cell survival.
- Further research is needed to fully elucidate the complex interactions between UPR, ERAD, and ER-phagy.
- This review highlights key advancements and future directions in the field.

01:25Cell Signaling in Plants
5.6K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:37The Unfolded Protein Response
4.6K
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
5.2K
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...

01:32Export of Misfolded Proteins out of the ER
3.6K
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...

01:17Role of ER in the Secretory Pathway
5.4K
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...
