Locus Delta in the Notch signaling system: organization and pleiotropic function during Drosophila development

Delta locus is the important component of the Delta-Notch signaling system implicating in a general mechanism of local cell signaling. Delta and Notch encode the evolutionary conserved cell surface proteins that interact and function as ligand (DELTA) and receptor (NOTCH) in a wide variety of cell fate specification events during oogenesis, embryogenesis and metamorphosis.
