dumpy interacts with a large number of genes in the developing wing of Drosophila melanogaster.

The complex Drosophila dumpy gene encodes a gigantic protein located in the apical extracellular matrix of epithelial cells. It has been shown to interact with several proteins notably during embryonic tracheal development. Here we examine Dumpy's interactions in vivo with mutations in 20 genes previously recovered in a screen for recessive lethals that generate blisters when somatic clones are produced by mitotic crossing over during wing development.
