Export 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...

Protein Denaturation01:28

Protein Denaturation

4.2K
The function of proteins depends on their native three-dimensional structure, which is dictated by the amino acid sequence of the specific protein. Folding of the polypeptide chain takes place under specific conditions that energetically favor the folded conformation. In contrast, protein denaturation occurs spontaneously under unfavorable conditions that disrupt the integrity of the folded conformation. Thus, the chemical and physical environment of a protein, such as significant changes in pH...

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Protein Folding01:25

Protein Folding

8.0K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Viral Mutations00:36

Viral Mutations

32.3K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Area of Science:

  • Structural Biology
  • Bioinformatics
  • Computational Biology

Background:

  • Advancements in protein structure prediction, such as AlphaFold2, enable studies on protein dynamics and mutation effects.
  • Assessing alternative protein conformations and the impact of mutations requires specialized tools.

Purpose of the Study:

  • To introduce MutAmore, a bioinformatics tool for visualizing protein structural changes due to mutations.
  • To provide a qualitative assessment of the mutational landscape through dynamic 3D mutation movies.

Main Methods:

  • MutAmore generates all possible single amino-acid variations (SAVs) for a given protein sequence.
  • It predicts 3D structural conformations for all variants using state-of-the-art models.
  • The tool visualizes mutation data and creates color-coded 3D animations, supporting user-inputted experimental structures.

Main Results:

  • MutAmore creates dynamic 3D movies illustrating the structural impact of SAVs.
  • The bioinformatics tool generates a mutation matrix and color-coded animations for intuitive visualization.
  • It offers a flexible pipeline for generating protein mutation movies.

Conclusions:

  • MutAmore facilitates the study of protein dynamics and the structural consequences of mutations in the post-AlphaFold2 era.
  • The tool aids in understanding the dynamical space accessible from SAVs by sampling alternative protein configurations.
  • It supports the exploration of alternative protein conformations and the structural impact of mutations.
