UASt regulatory sequences drive expression of a cDNA encoding 93bp of the 5' untranslated region (splice variant A) and the entire coding sequence of Cad99C. The protein is tagged at the C-terminal end with a triple Tag:HA tag.
follicle cell | somatic clone, with Scer\GAL4Act5C.PP
microvillus | somatic clone, with Scer\GAL4Act5C.PP
Follicle cell clones expressing Cad99CScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Act5C.PP have abnormal bundles of microvilli.
