Contrary to the prevailing view of N-glycosylation as a ...One-fifth of human proteins are N-glycosylated in the endoplasmic reticulum (ER) by two oligosaccharyltransferases, OST-A and OST-B. Contrary to the prevailing view of N-glycosylation as a housekeeping function, we identified an ER pathway that modulates the activity of OST-A. Genetic analyses linked OST-A to HSP90B1, an ER chaperone for membrane receptors, and CCDC134, an ER luminal protein. During its translocation into the ER, an N-terminal peptide in HSP90B1 templates the assembly of a translocon complex containing CCDC134 and OST-A that protects HSP90B1 during folding, preventing its hyperglycosylation and degradation. Disruption of this pathway impairs WNT and IGF1R signaling and causes the bone developmental disorder osteogenesis imperfecta. Thus, N-glycosylation can be regulated by specificity factors in the ER to control cell surface receptor signaling and tissue development. | |||||||||
