DLL3

From Wikipedia, the free encyclopedia

Template:Short description An Error has occurred retrieving Wikidata item for infobox 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.

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.[2] Expression of DLL3 is highest in fetal brain. It plays a key role in somitogenesis within the paraxial mesoderm.[3]

Clinical significance

Mutations in this gene cause the autosomal recessive genetic disorder Jarcho-Levin syndrome.[4] Expression of the gene occurs in Neuroendocrine tumors, which has been targeted as a potential pathway for treatment.[5]

Experimental drugs targeting DLL3 have been investigated as a possible treatment for lung cancer including Tarlatamab and rovalpituzumab tesirine.[6]
