UAS sequences drive a cDNA that consists of the CRD and C terminal domains of fz2 and the transmembrane domain of fz. This has been tagged with Tag:MYC in the non-conserved region in between the CRD and the transmembrane domains.
When fz::fz22-1-2.Scer\UAS.T:Hsap\MYC is driven by Scer\GAL4en-e16E large nicks are never seen in the wing margin.
