Description

Insertion maps less than 100bp upstream of a BalI site located 4bp upstream from the transcription start site. The P-element 31bp inverted terminal repeats are conserved.

(Howes et al., 1988)

1.0kb insertion within the 489bp HindIII/BalI fragment located just upstream of the transcriptional start site.
