Midkine (MK) and Pleiotrophin (PTN) are small heparin-binding cytokines with closely related structures. To date, this family of proteins has been implicated in multiple processes, such as growth, survival, and migration of various cells, and has roles in neurogenesis and epithelial-mesenchymal interaction during organogenesis. In this report, we have characterized two members of the MK/PTN family of proteins in Drosophila, named Miple1 and Miple2, from Midkine and Pleiotrophin. Drosophila miple1 and miple2 encode secreted proteins which are expressed in spatially restricted, nonoverlapping patterns during embryogenesis. Expression of miple1 can be found at high levels in the central nervous system, while miple2 is strongly expressed in the developing midgut endoderm. The identification of homologues of the MK/PTN family in this genetically tractable model organism should allow an analysis of their function during complex developmental processes.
