A set of transgenic insertion stocks derived by TE mobilization using the P-element construct P{GT1}. The P{GT1} construct is described as a dual-tagged gene trap (FBrf0132344):it carries (1) w+mGT1 mini-white marker, designed to confer a pigmented eye phenotype only if the construct is inserted within a host gene, and (2) a promoter-less Scer\GAL4 gene which is expressed if it is produced as a fusion with the mRNA produced by the host gene. The construct also carries a Tn\neoR selectable marker (FBrf0132344).
3' RACE supports additional insertion into CG8771.
Location 3L:19143599-19143600 confirmed by FlyBase alignment of dbGSS accession BH023745 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation confirmed.
Mutants exhibit a quantitative gain of bristles.Insertion is 8 kb upstream of the fz2 gene.
