Rabbit anti Human Delta-like Protein 4 antibody detects human Delta-like protein 4 (DLL4), also known as Delta-4. DLL4 is a 685 amino acid single pass type 1 transmembrane glycoprotein of ~72 kDa containing a single DSL domain and eight EGF-like domains. Human DLL4 is the homologue of the Drosophila delta protein, and functions as a transmembrane bound ligand to the Notch receptor, Notch1.
DLL4 is expressed in the vasculature and plays a critical role in vascular development. It is induced by vascular endothelial growth factor (VEGF), as a negative feedback regulator to regulate angiogenic sprouting and promote the formation of a differentiated vascular network (Mailhos et al. 2001). DLL4 has been found to be strongly expressed in tumour vessels of primary renal tumours (Patel et al. 2005) and bladder cancer (Patel et al. 2006), and inhibition of DLL4 results in increased vascular proliferation but defective maturation. This in turn leads to a decrease in tumour growth, with no apparent toxicity (Ridgway et al. 2006).
Expression of DLL4 in normal human dermis is low in foetal tissues, becomes more intense during early life (0-20 years) and gradually declines thereafter as shown by immunohistochemical studies on FFPE tissues using rabbit anti human DLL4 antibody (Gunin et al. 2014).
