Proteins that traffic through the eukaryotic secretory pathway are commonly modified with N-linked carbohydrates. These bulky amphipathic modifications at asparagines intrinsically enhance solubility and folding energetics through carbohydrate-protein interactions. N-linked glycans can also extrinsically enhance glycoprotein folding by utilizing the glycoprotein homeostasis or “glycoproteostasis” network, comprising numerous glycan binding and/or modification enzymes or proteins that synthesize, transfer, sculpt and utilize N-linked glycans to direct folding vs. degradation, and trafficking of nascent N-glycoproteins through the cellular secretory pathway. If protein maturation is perturbed by misfolding and/or aggregation, stress pathways are often activated that result in transcriptional remodeling of the secretory pathway, in an attempt to alleviate the insult(s). The inability to achieve glycoproteostasis is linked to several pathologies, including amyloidoses, cystic fibrosis, and lysosomal storage diseases. Recent progress on genetic and pharmacologic adaptation of the glycoproteostasis network provides hope that drugs can be developed for these maladies in the near future.
