Overview

A deletion screen for phenotypes of dilated cardiomyopathy, defined as enlarged end-diastolic and end-systolic dimensions, and impaired fractional shortening, was conducted in Drosophila. This resulted in the identification of a causative gene that was subsequently determined to encode a Notch ligand; the gene was given the name weary (wry). There are several low-scoring orthologs of Dmel\wry in human.

Using the GAL4/GAL80-ts system to precisely target expression in the fly adult heart, RNAi-effected loss of wry expression results in inducible and reversible dilated cardiomyopathy. Cardiac-specific expression of a transgenic wild-type copy of wry rescues the dilated cardiomyopathy phenotype of the deletion. Extending this analysis to other Notch signaling components, cardiac-specific expression of N, Dl, or Ser was also observed to rescue the dilated cardiomyopathy phenotype of the deletion.

For transgenic human constructs, fly transgenic constructs and classical alleles, detailed phenotypic descriptions can be found in the allele reports; allele reports can be accessed from the gene report or by clicking on the allele symbols in the Disease Ontology and Reagent tables below.

        Gene Snapshot
        Delta (Delta) encodes a single pass transmembrane EGF family protein and one of two ligands of the Notch signaling pathway. It regulates cell fate decisions and cell proliferation. Post transcriptional modification (such as by fucosylation, ubiquitination and proteolysis) of the product of Delta is key for its functions. [Date last reviewed: 2019-03-07]

        Comments on ortholog(s)

        Moderate- to high-scoring ortholog of human DLL1 and DLL4; Dmel\Dl shares 39% identity and 51-53% similarity with the human genes.
