Background Information

DLL4, also named as Delta4, plays a role in the Notch signaling pathway. It activates Notch-1 and Notch-4. Notch signaling is activated upon engagement of the Notch receptor with its ligands, the DSL (Delta, Serrate, Lag2) proteins of single-pass type I membrane proteins. DLL4 is highly expressed in the vascular endothelium and is involved in angiogenesis.
