jbug genomic fragment truncated after the exon containing the first transcriptional stop. Sequence for a GFP tag is inserted into the sixth coding exon 6 (same location as in jbugGFP). It results in expression of GFP-tagged proteins from jbug transcript RL and the expression of untagged proteins from transcripts RC, RG, RH, RJ and RK under native control.
jbugMGGM.GFP can rescue the wing blister phenotypes of alleles of the moa complementation group.
