Description and Uses
Description

Transgenic construct in which y and w are used as reporters in an enhancer blocking assay; construct used to study the gypsy\su(Hw)BR insulator. Contains the y+t7.7 minigene, which includes partially overlapping body and wing enhancers located, respectively, at positions -1266 to -1963 and -1808 to -2873 relative to the transcription start site. An FRT cassette containing the w eye-specific enhancer is inserted between the y wing and body enhancers. A 430bp gypsy\su(Hw)BR insulator sequence (containing 12 su(Hw) protein binding sites) has been between the y enhancers and the y coding region. A second copy of this gypsy\su(Hw)BR insulator sequence has been inserted downstream of the y coding region, followed by the w+mC minigene.
