Description

P-element insertion in the first exon, upstream of the translation start site.

(Lam and Tsubota, 2004)

P-element is inserted into the 5' untranslated region of the mod(r) transcript, 20bp downstream from the putative start of transcription.

      Statement
      Reference

      Suppresses the wing truncation associated with hypomorphic r alleles, e.g. rhd1. Does not suppress the sterility of r females.
