ERdj5, a member of the protein disulfide isomerase (PDI) family, serves to eliminate misfolded proteins by reducing aberrantly formed disulfide bonds. This work revealed a new crystal structure and conformational dynamics of ERdj5, elucidating molecular mechanisms of protein quality control in the endoplasmic reticulum. The present findings provide molecular insights into neurodegenerative diseases and diabetes caused by accumulation of misfolded proteins.
