NOTCH1 is activated by DLL4 ligand expressed on a neighboring cell. The interaction of NOTCH1 and DLL4 is enhanced when NOTCH1 is glycosylated by fringe-enzymes. Based on mouse studies, activation of NOTCH1 by DLL4 may be important in angiogenesis (Benedito et al. 2009). DLL4 may also be involved in T-cell development. Mouse Dll4 is expressed on thymic epithelial cells and its interaction with Notch1 expressed on hematopoietic progenitors is necessary for T-cell lineage commitment (Koch et al. 2008, Hozumi et al. 2008).
