Contains a genomic fragment centred on Rab9 in which part of the Rab9 open reading frame (extending from the ATG to the end of the ATG-containing exon) has been replaced with the GAL4 driver coding region and a loxP cassette containing Disc\RFP3xP3.PC and the kanamycin resistance gene.
Scer\GAL4Rab9.ATG drives expression in the glial cells of the blood-brain barrier (BBB).
ScerGAL4Rab9.ATG drives expression in some neurons and glia in the larval brain, as well as in the developing photoreceptors in the eye disc. In the pupal and adult brain, expression in confined to glial cells and some neurons of the olfactory system.
