Contains a genomic fragment centred on Rab27 in which the complete Rab27 open reading frame has been replaced with the GAL4 driver coding region and a loxP cassette containing Disc\RFP3xP3.PC and the kanamycin resistance gene.
ScerGAL4Rab27.ORF drives expression in many neurons and possibly glia in the larval brain. In the pupal and adult, expression in the brain is restricted to a few central neurons, including the mushroom bodies. Expression in the adult mushroom body is stronger than in the pupal one.
The PBac{I-SceI(FRT.Rab27-GAL4.ORF(loxP.3xP3-RFP))} vector can be used both as a driver expressing Scer\GAL4 under the control of the Rab27 regulatory sequences present in the construct and also as a donor construct for ends-out homologous recombination at the endogenous Rab27 locus.
