Neurogenic locus notch homolog protein 3 (Notch 3) is a protein that in humans is encoded by the NOTCH3 gene.

Function

This gene encodes the third discovered human homologue of the Drosophila melanogaster type I membrane protein notch. In Drosophila, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signalling pathway that plays a key role in neural development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remains to be determined.

Pathology

Mutations in NOTCH3 have been identified as the underlying cause of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Mutations in NOTCH3 have also been identified in families with Alzheimer's disease. Adult Notch3 knock-out mice show incomplete neuronal maturation in the spinal cord dorsal horn, resulting in permanently increased nociceptive sensitivity. Mutations in NOTCH3 are associated to lateral meningocele syndrome.

Pharmaceutical target

Notch3 is being investigated as a target for anti-cancer drugs, as it is overexpressed in several types of cancers. Early clinical trials of Pfizer's PF-06650808, an anti-Notch3 antibody linked to a cytotoxic drug, showed efficacy against solid tumors.

Mammalian evolution

A recent study analyzed the NOTCH3 gene across 113 mammalian species to understand its evolution and links to human disease. The researchers discovered unusual natural variations, including eight cysteine changes in jaguar, a rare human-specific isoform shared with a few other mammals, and a unique regulatory deletion in Brandt’s bat. In humans, mutations in NOTCH3 can cause CADASIL, a hereditary small-vessel disease affecting the brain, but these variations appear harmless in other mammals. The NOTCH3 protein has high homology among mammals, and structural or functional information from these species may aid research on NOTCH3-related conditions in humans, such as CADASIL. The study combines evolutionary genomics and protein structure analysis to reveal previously hidden functional elements. These findings provide insights into how evolutionary differences can influence protein function and disease susceptibility.
