Transgenic construct used in a study of the Fab-7 element. Contains two divergently transcribed reporters: a w+C marker and a lacZ reporter driven by a minimal eve promoter. A 200bp SpeI-BamHI enhancer fragment that directs expression of the h stripe 1 (H1), a 1.2kb fragment of the Fab-7 element and a 1kb SalI IAB5 enhancer fragment from the iab-5 cis regulatory region of Abd-B have been inserted between the two divergent promoters.
Consists of a 1231bp PstI-ApaI fragment including the Fab-7 insulator.
A 1.2kb XhoI-NotI fragment corresponding to the minimal Fab-7 boundary element.
Construct: 1.2kb Fab-7 DNA fragment that spans nucleotide positions 84,594 to 83,423 within the complete BX-C sequence and contains all three DNaseI hypersensitive sites.
