P{SUPor-P-lt} contains a mini-w gene that has two flanking gypsy\su(Hw)BR sites, one of which is upstream of the w eye promoter.
Construct: w+mC minigene altered to include a su(Hw) binding region (all 12 binding sites, nucleotides 647 to 1077 of Marlor et al., Mol Cell Biol 6:1129-1134 ), upstream of the w eye enhancer (nucleotides -1084 to -1465 of Qian et al., Genetics 131:79-90 ), upstream of the w coding region, upstream of a second su(Hw) binding region.
Two gypsy\su(Hw)BR binding sites flank the w+mET sequences to insulate the w gene from chromosomal position effects.
Construct: 1.6kb StyI-EcoRI fragment containing the Ubx PRE (Polycomb group response element).
Construct: Consists of a 430bp gypsy\su(Hw)BR, including all 12 binding sites.
Consists of a 430bp gypsy\su(Hw)BR, including all 12 binding sites, nucleotides 647 to 1077 of FBrf0045014.
Consists of a 430bp gypsy\su(Hw)BR, gypsy sequences 647-1077 (coordinates of FBrf0045014).
Constructs P{SUPor-P.PRE#2} and P{SUPor-P.PRE#6} differ in the orientation of the fragment containing the y enhancer, y coding region and UbxPRE. In construct P{SUPor-P.PRE#6} the y gene is transcribed in the opposite orientation to the w gene present in P{SUPor-P.PRE#6}. In construct P{SUPor-P.PRE#2}, the fragment containing the y enhancer, y coding region and UbxPRE has been reversed so that the y gene is transcribed in the same orientation as the w gene.
