WebProtein misfolding is a common cellular event that can occur throughout the lifetime of a cell, caused by different events including genetic mutations, translational errors, abnormal … 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.
