DLL3
Protein-coding gene in the species Homo sapiens
From Wikipedia, the free encyclopedia
Delta-like 3 (Drosophila), also known as DLL3, is a protein which in humans is encoded by the DLL3 gene.[5] Two transcript variants encoding distinct isoforms have been identified for this gene.

Function
This gene encodes a member of the delta protein ligand family. This family functions as Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain.[6] Expression of DLL3 is highest in fetal brain. It plays a key role in somitogenesis within the paraxial mesoderm.[7]
Clinical significance
Mutations in this gene cause the autosomal recessive genetic disorder Jarcho-Levin syndrome.[8] Expression of the gene occurs in Neuroendocrine tumors, which has been targeted as a potential pathway for treatment.[9]
Experimental drugs targetting DLL3 have been investigated as a possible treatment for lung cancer including Tarlatamab and rovalpituzumab tesirine.[10]
