Secretory and transmembrane proteins originate in the Endoplasmic Reticulum (ER). Protein folding helpers, the chaperones, aid their folding and decide whether a protein is secreted or degraded. This work established Grp170 as a member of the ER chaperone machinery by showing its
in vivo binding to various substrates, which we found to be regulated by unique intramolecular mechanisms. Through the engineering of a novel
in vivo peptide library screen, hitherto unknown specific binding sites of Grp170 and other ER chaperones within their substrates were identified. Insights into chaperone binding patterns are crucial to understand cellular quality control and provide a means for optimizing protein production in mammalian cells.
