Pax genes play pivotal roles in regulating diverse signal transduction path- ways and organogenesis during embryonic development through modulating cell proliferation and self-renewal, embryonic precursor cell migration, and the coordination of specific differentiation programs. Ten members of the Pax gene family, which perform crucial regulatory functions during embryonic and postembryonic development, have been identified in Drosophila . In this report, we described the protein structures, expression patterns, and main functions of Drosophila Pax genes.
