Delta-like 3 (Drosophila), also known as DLL3, is a protein which in humans is encoded by the DLL3 gene.[1] Two transcript variants encoding distinct isoforms have been identified for this gene.


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.[2]

Clinical significance[edit]

Mutations in this gene cause autosomal recessive spondylocostal dysostosis 1.[3]
