Imprecise excision of P{GawB}Abd-BLDN resulting in a 1.2 kb deletion removing 53 bp of the promoter tethering element (PTE) sequence 5' of the original P{GawB}Abd-BLDN insertion site, as well as 1134 bp of endogenous genomic sequence 5' of the defined PTE. A portion of the Scer\GAL4 sequence from the original P{GawB}Abd-BLDN remains, along with 202 bp of the 3' PTE sequence
Deletion resulting from the imprecise excision of P{GawB}Abd-BLDN, which removes sequence between -241 and -1428 relative to the Abd-B-RB transcription start site according to GB:U31961. 476 bp of P element sequences remain at the excision site.
