Encompassing Amino Acids: 27-529
Application: Useful to study the binding of DLL4 in ELISA and in cellular assays.
Background: DLL4, or delta-like canonical Notch ligand 4, is part of the Notch signaling pathway and it is involved in normal tissue development and homeostasis. It is an agonist ligand and can bind to the four Notch receptors. It is expressed in the vascular system and plays a crucial role in angiogenesis. Loss of function of DLL4 results in VEGF upregulation, and the formation of immature vessels without a lumen. It has been shown that DLL4 inhibition can actually result in tumor regression by its role on VEGF upregulation. DLL4 is found in several tumor types, and it is found in tumor stem cells. Inhibition of DLL4 can thus contribute to cancer therapy via its several mechanisms of action.
