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.

Contents

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]

<span class="mw-page-title-main">HES7 gene</span> Protein-coding gene in humans

(HES7) or bHLHb37 is protein coding mammalian gene found on chromosome 17 in humans. HES7 is a member of the Hairy and Enhancer of Split families of Basic helix-loop-helix proteins. The gene product is a transcription factor and is expressed cyclically in the presomitic mesoderm as part of the Notch signalling pathway. HES7 is involved in the segmentation of somites from the presomitic mesoderm in vertebrates. The HES7 gene is self-regulated by a negative feedback loop in which the gene product can bind to its own promoter. This causes the gene to be expressed in an oscillatory manner. The HES7 protein also represses expression of Lunatic Fringe (LFNG) thereby both directly and indirectly regulating the Notch signalling pathway. Mutations in HES7 can result in deformities of the spine, ribs and heart. Spondylocostal dysostosis is a common disease caused by mutations in the HES7 gene. The inheritance pattern of Spondylocostal dysostosis is autosomal recessive.
