A 2kb Pis genomic region (corresponding to -2100 to -10bp of the Pis gene) drives expression of Hsap\CDIPT.
Hsap\CDIPTPis.PW is a suppressor of lethal | embryonic stage phenotype of Pis1
Hsap\CDIPTPis.PW is a suppressor of eye | somatic clone phenotype of Pis1
Hsap\CDIPTPis.PW is a suppressor of eye photoreceptor cell | somatic clone phenotype of Pis1
Expression of Hsap\CDIPTPis.PW rescues both the embryonic lethality and the eye phenotype of Pis1 flies. Rescue of eyes is complete as the ERG response of rescued flies is indistinguishable from wild type.
