Genetically engineered deletion of rpk. Boundaries determined from primer sequences (4 base ambiguity due to repeat at ends).
Df(3R)rpk-Karyβ3 animals carrying PBac{CH321-22I15.Δrpk} (restoring Karyβ3 but not rpk function) are viable at larval stages, but have somewhat reduced viability at the adult stage.
Df(3R)rpk-Karyβ3 larvae carrying PBac{CH321-22I15.Δrpk} show a strongly reduced response to gentle touch compared to controls.
