A sfGFP tag has been inserted into the endogenous Su(z)12 locus, near the N-terminal end of the open reading frame.
majority die during embryonic stage | maternal effect, with JabbaUASp.VHH(GFP4), Scer\GAL4VP16.mat.αTub67C
Mislocalization of Su(z)12sfGFP during oogenesis by expressing the JabbaUASp.vhhGFP4 nanobody under the control of Scer\GAL4VP16.mat.αTub67C leads to almost complete embryonic lethality of the progeny.
