Description

4kb genomic fragment that contains the Sply gene, including 491bp of upstream regulatory sequences and the 3'UTR. The coding region has been mutated to contain the S335I amino acid replacement, which is equivalent to the disease-associated S346I mutation in the orthologous human SGPL1 gene. A Tag:HA tag has been inserted at the C-terminal end of the Sply open reading frame.

      Either the SplyS335I.T:Ivir\HA1 or the SplyR210Q.T:Ivir\HA1 allele of Sply bearing mutations discovered to be disease-associated in its human ortholog SPGL1 fail to ameliorate the phenotype of Sply05091 mutants, the Drosophila model of nephrotic syndrome. The mutant phenotype can be rescued by combination with SplyE119G.T:Ivir\HA1.

      Fails to rescue

      SplyS335I.Tag:HA fails to rescue Df(2R)BSC433/Sply05091

      (Lovric et al., 2017)
      Comments

      The reduced density of foot process in garland cell nephrocytes observed in Sply05091/Df(2R)BSC433 third instar larvae cannot be rescued by combination with SplyS335I.T:Ivir\HA1.
