Protein misfolding causes what
Did you know?
A protein is considered to be misfolded if it cannot achieve its normal native state. This can be due to mutations in the amino acid sequence or a disruption of the normal folding process by external factors. The misfolded protein typically contains β-sheets that are organized in a supramolecular arrangement known as a cross-β structure. These β-sheet-rich assemblies are very stable, very insoluble, and generally resistant to proteolysis. The structural stability of these fibrillar assembli… WebbProtein misfolding disease: disease due to misfolding of a protein, which is either degraded or accumulated/ aggregated in the cell PQC: protein quality control Molecular …
