FlyBase curator comment: this entry represents a transgenic construct where the particular construct used cannot be determined.
The functional and structural defects in Drosophila nephrocytes expressing RNAi against cindr (Drosophila ortholog of CD2AP) are rescued by expression of wt version of human CDAP but not by the nephrotic syndrome-related mutant version carrying the K301M mutation.
Adult flies expressing cindrTRiP.cUa under the control of Scer\GAL4Dot.PK display nephrocyte functional defects (measured by uptake assays) and reduced adult lifespan relative to controls. On the ultrastructural level, knockdown of cindr results in fusion of discreet nephrocyte slit diaphragm units into semi-continuous wavelike form and loss of lacunar channels.
Adult flies expressing cindrdsRNA.Scer\UAS.cUa under the control of Scer\GAL4sns.GCN lack pericardial nephrocytes but show no difference in lifespan compared to wild-type controls.
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has short lived phenotype, suppressible | partially by Hsap\CD2APUAS.cFa, Scer\GAL4Ugt36A1.PK
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has short lived phenotype, non-suppressible by Hsap\CD2APK301M.UAS, Scer\GAL4Ugt36A1.PK
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has adult pericardial cell phenotype, suppressible | partially by Hsap\CD2APUAS.cFa, Scer\GAL4Ugt36A1.PK
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has nephrocyte diaphragm | adult stage phenotype, suppressible | partially by Hsap\CD2APUAS.cFa, Scer\GAL4Ugt36A1.PK
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has adult pericardial cell phenotype, non-suppressible by Hsap\CD2APK301M.UAS, Scer\GAL4Ugt36A1.PK
Scer\GAL4Ugt36A1.PK, cindrRNAi.UAS.cUa has nephrocyte diaphragm | adult stage phenotype, non-suppressible by Hsap\CD2APK301M.UAS, Scer\GAL4Ugt36A1.PK
The nephrocyte functional defects (measured by uptake assays) as well as structural abnormalities (fusion of the slit diaphragm structures, loss of lacunar channel) and reduced adult lifespan characteristic for flies expressing cindrTRiP.cUa under the control of Scer\GAL4Dot.PK are significantly improved by co-expression of Hsap\CD2APUAS.cFa but not Hsap\CD2APK301M.UAS.
