Delta-like protein 3 (DLL3) is a transmembrane protein that belongs to the Delta/Serrate/Lag-2 (DSL) family of Notch ligands. Mature human DLL3 consists of a 466 amino acid (aa) extracellular domain (ECD) with one DSL domain and six EGF-like repeats, a 21 aa transmembrane segment, and a 105 aa cytoplasmic domain. Within the ECD, human DLL3 shares 86% aa sequence identity with mouse and rat DLL3. DLL3 is known as a divergent DSL ligand since it does not function in similar manner as the rest of DSL ligands. It does not activate Notch signaling through trans-activation, but autonomously attenuates signaling induced by other DSL ligands. A loss-of-function mutation of DLL3 is linked to axial skeletal defects in the spondylocostal dysplasia, which is linked to abnormal Notch signaling. DL-3 promotes proliferation and inhibits apoptosis of cancer cells. The proliferative effect mediated by DLL3 is thought to be due to increased Akt phosphorylation in cancer cells.
