Like other membrane proteins, newly translated PMP22 protein is temporarily sequestered to the endoplasmic reticulum (ER) and Golgi apparatus for post-translational modifications. PMP22 protein is glycosylated with an N terminus-linked sugar and co-localized with the chaperone protein calnexin in the ER. After the protein is transported to the Golgi apparatus it can then become incorporated in the plasma membrane of the cell.
