Background: DLL3

Delta-like protein 3 (DLL3) is a transmembrane protein that belongs to the Delta/Serrate/Lag-2 (DSL) family of Notch ligands (1). 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 (2). 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 (3). A loss-of-function mutation of DLL3 is linked to axial skeletal defects in the spondylocostal dysplasia, which is linked to abnormal Notch signaling (4). 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 (5).
