4kb genomic fragment that contains the wild-type Sply gene, including 491bp of upstream regulatory sequences and the 3'UTR. A Tag:HA tag has been inserted at the C-terminal end of the Sply open reading frame.
The reduced density of foot process in garland cell nephrocytes observed in Sply05091/Df(2R)BSC433 third instar larvae is rescued by combination with SplyWT.T:Ivir\HA1.
