Consists of genomic sequences from the intron of the Bin1 gene to approximately 1100bp into the sra intron, followed by a region within the sra intron that is about 170bp upstream of the splice acceptor site to a position in the 3' UTR of the CG6126 gene. The resulting transgene has all sra codons but lacks the majority of the sra intron, and has the entire intergenic regions separating sra from its flanking genes, plus 22 codons of Bin1 but no coding sequence from CG6126.
