The transmembrane signaling protein Notch, which is crucial for embryonic cell
fate decisions, has 36 extracellular EGF domains that are glycosylated in
variable and complex ways. A new study shows that O-fucose and O-glucose
stabilize the repeats but that extension of glucose by xylose weakens stability,
explained by the binding of the glycan to a protein groove. This work shows how
different types of glycosylation can distinctly influence protein stability and
structure.
