A 500bp fragment containing the 5'UTR and upstream promoter region of the testis-specific isoform of ScsβA is fused to the ORF of the somatic (S) isoform of ScsβA and a Tag:HA tag, followed by a 200bp 3'UTR fragment of the testis isoform of ScsβA.
ScsβAS.Tag:HA rescues ScsβACC06238/Df(3R)osk
Expression of skapS.T:Ivir\HA1 fully rescues the sterility and sperm individualization defects of skapCC06238/Df(3R)osk mutants.
