Delta-like Ligand 4 (DLL4)

Target
DLL4
Molecular classification
Transmembrane protein, Notch ligand, Delta/Serrate/LAG-2 (DSL) family
01

Overview

Delta-like ligand 4 (DLL4) is a transmembrane protein and a ligand for Notch receptors, playing a critical role in vascular development, cardiac formation, and immune regulation. It functions as a negative regulator of angiogenic sprouting and is involved in macrophage activation, making it a potential therapeutic target for various cardiovascular, metabolic, and inflammatory disorders. Precise regulation of DLL4-Notch signaling is essential for normal development and tissue homeostasis.
