Summary
Targeting peripheral protein quality control (PeriQC) degradation of cystic fibrosis transmembrane conductance regulator (CFTR) offers a new therapeutic strategy. Counteracting CFTR ubiquitination in PeriQC can enhance treatment efficacy for cystic fibrosis.
Area of Science:
- Biochemistry
- Cell Biology
- Genetics
Background:
- Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated anion channel crucial for epithelial cell function.
- Mutations in CFTR cause cystic fibrosis (CF), a common genetic disorder, often leading to protein misfolding and degradation.
- Current therapies face limitations as even PM-localized CFTR is degraded by peripheral protein quality control (PeriQC).
Conclusions:
- Targeting CFTR ubiquitination in PeriQC presents a promising therapeutic avenue for cystic fibrosis.
- Developing strategies to counteract PeriQC-mediated degradation can enhance the efficacy of existing and future CF treatments.
- Further research into CFTR PeriQC mechanisms may unlock novel treatment modalities.

02:58Regulated Protein Degradation
7.4K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

01:29Protein Folding Quality Check in the RER
3.8K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

01:32Export of Misfolded Proteins out of the ER
3.7K
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...

02:04Covalently Linked Protein Regulators
6.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

01:13The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
