A 5.8 kb genomic fragment flanking the start of the eya-RA cDNA regulates expression of a GAL4 driver.
ScerGAL4A3.eya drives strong expression in male somatic cyst cells; expression is stronger than that of ScerGAL4PpY-55A.PJ.
Drives low level expression in male germline cyst progenitor cells and high levels in cyst cells.
