ERO1L alpha Proteins and Enzymes

Perhaps the most distinctive feature of protein folding in the ER is the abundance of disulfide bonds that must form during maturation of proteins traveling along the secretory pathway. Formation of disulfide bonds is a redox reaction. Thus, to match the flux of disulfide bonds that exit from the ER by virtue of protein secretion, a flux of oxidizing equivalents into the ER is required. In eukaryotic cells, the essential protein relay supporting this flux, and hence disulfide bond formation, ...
