UASt regulates expression of the wild type/ancestral (G0) Hsap\APOL1 gene.
The expression of Hsap\APOL1G0.UAS.cKa under the control of Scer\GAL4GMR.PU induces a small frequency of a 'rough eye' phenotype.
Adult pericardial nephrocytes expressing Hsap\APOL1G0.UAS.cKa under the control of Scer\GAL4Ugt36A1.PK exhibit a mild increase in uptake function, as compared to controls.
