Generated by imprecise excision of P{RS3}UM-8171-3, resulting in a deletion of genomic sequence from -660 to +2250 bp relative to the transcription start site of transcript vfl-RB. Part of the P element remains.
Deletion resulting from imprecise excision of P{RS3}UM-8171-3. Reported as a deletion from -660 to +2250 relative to the zld transcription start site (defined by the start site of zld-RB in earlier FlyBase releases, e.g. r5.1).
