How does protein misfolding occur
WebJan 1, 2024 · Using these cells, we discovered that random errors tend to affect the structural integrity of proteins, which induces protein misfolding [17]. Most amino acids are part of structural motifs, so replacing a hydrophobic amino acid with a hydrophilic one (or vice versa) can result in protein misfolding [31]. Similar problems arise when other ... WebProtein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases.
