Imprecise excision of the progenitor insertion, resulting in a 80.0kb deletion which removes all of Rab9 except the most 5' exon.
Rab956/Rab9199 is rescued by Rab9UAS.EGFP/Scer\GAL4btl.PS
Expression of Rab9Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4btl.PS rescues the increased dorsal trunk tube length seen in Rab956/Rab9199 embryos.
