Ligand binding induces a conformational change in NOTCH3, probably through mechanical pulling of NOTCH3 triggered by endocytosis of the receptor-attached ubiquitinated ligand. This conformational change exposes the S2 site in the extracellular region of NOTCH3 and triggers cleavage of NOTCH3 by ADAM10 metalloprotease, generating the membrane-anchored NOTCH3 fragment NEXT3 (Groot et al. 2014). The extracellular NOTCH3 portion remains attached to the ligand presented on the plasma membrane of a neighboring cell.
