Delta-like protein 4/DLL4 Protein, Human (HEK293, His-Avi)

Delta-like protein 4 (DLL4) functions as a Notch ligand and activates NOTCH1 and NOTCH4 in the Notch signaling pathway. It regulates angiogenesis by inhibiting endothelial cell proliferation, migration, and angiogenesis. Delta-like protein 4/DLL4 Protein, Human (HEK293, His-Avi) is the recombinant human-derived Delta-like protein 4/DLL4 protein, expressed by HEK293 , with labeled tag. The total length of Delta-like protein 4/DLL4 Protein, Human (HEK293, His-Avi) is 498 a.a., with molecular weight of 62-68 kDa.

Delta-like protein 4 (DLL4) is a key participant in the Notch signaling pathway, acting as a Notch ligand with functional implications. It specifically activates NOTCH1 and NOTCH4, contributing to the intricate cellular communication within this signaling cascade. Beyond its role in Notch signaling, DLL4 emerges as a crucial regulator of angiogenesis, exerting a negative influence on endothelial cell proliferation, migration, and angiogenic sprouting. The protein's indispensability extends to retinal progenitor proliferation, where it plays a vital role in suppressing rod fates in late retinal progenitors and ensuring the proper generation of diverse retinal cell types. Additionally, during spinal cord neurogenesis, DLL4 inhibits V2a interneuron fate, adding another layer to its multifaceted functions. The molecular interactions involving DLL4 include its engagement with NOTCH4 and NOTCH1, facilitated by specific domains in DLL4 and NOTCH1, respectively.
