Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B IP
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. The DSL proteins contain multiple EGF-like repeats and a DSL domain that is required for binding to Notch (1,2). Five DSL proteins have been identified in mammals: Jagged1, Jagged2, Delta-like (DLL) 1, 3 and 4 (3). Ligand binding to the Notch receptor results in two sequential proteolytic cleavages of the receptor by the ADAM protease and the -secretase complex. The intracellular domain of Notch is released and then translocates to the nucleus where it activates transcription. Notch ligands may also be processed in a way similiar to Notch, suggesting a bi-directional signaling through receptor-ligand interactions (4-6). DLL4 expression is highly restricted to the vascular endothelium (7), and haploinsufficiency of DLL4 results in major defects in vascular systems in mouse (8-11). Blockade of DLL4 inhibits tumor growth in model systems (12-14).
