Expression of the cut locus in the Drosophila wing margin is required for cell type specification and is regulated by a distant enhancer.

Abstract excerpt

The cut locus is a complex gene whose function is necessary for specification of a number of cell types, including the external sensory organs. The cut wing class of mutations of the cut locus are homozygous viable and lack tissue from the wing margin, which is normally composed of external sensory organs and noninnervated bristles. Expression of cut was examined in the developing wings of wild-type and mutant...
