Imprecise excision of P{EP}Cad99CGE21034 results in a small deletion covering the 5'UTR of Cad99C.

microvillus & follicle cell (with Cad99C21-8)
Cad99C21-8/Cad99C21-6 mutant follicles exhibit a range of defects of microvilli. Microvilli appear substantially shorter than in wild-type. In many cases, apical protrusions appear reduced in number, and they form an irregular, spiky pattern, suggesting that microvilli are abnormally shaped and may be clumped. In other cases, no obvious protrusions are detected or only few microvilli with an abnormal, wavy shape protruded from the apical surface.
Expression of Cad99CScer\UAS.fl in follicle cells under the control of Scer\GAL4Scer\FRT.Rnor\CD2.Act5C rescues microvillus formation in a Cad99C21-5/Cad99C21-6 mutant background.
