A fragment of the Rh3 promoter (nucleotides -160 to -56) is attached to a fragment of the Rh4 promoter (nucleotides -63- to +85) which both drive expression of a GAL4 driver.
ScerGAL4Pan-R7 drives expression in all R7 photoreceptors under the control of portions of the Rh3 and Rh4 promoters.
Drives expression in all R7 photoreceptors.
