Peter Walter: Unfolding the UPR

Proteins that are secreted from the cell or inserted into the plasma membrane, transit through the endoplasmic reticulum where they are properly folded and assembled and may undergo post-translational modification. Walter tells the story of the exciting discovery made in his lab of the “unfolded protein response”, a feedback pathway that ensures that the cell makes enough ER to properly modify all the secreted proteins in the cell.
