UAS regulatory sequences drive expression of cv-2 truncated after G[381]. The construct is tagged at the C-terminal end with Tag:V5 and 6xTag:polyHis.
Scer\GAL4A9/cv-2N.UAS fails to rescue cv-2KO1
Expression of one copy of cv-2N.Scer\UAS under the control of Scer\GAL4A9 fails to rescue the posterior crossvein defects seen in homozygous cv-2KO1 mutants.
