Insertion 330bp downstream of the transcription start site.
Insertion in the first non-coding exon.
DgEP2241 mutant larvae raised at 25[o]C show a strong temperature preference that peaks at 18.3[o]C on a linear thermal gradient ranging from 12[0] to 35[o]C, in contrast to wild-type larvae which have a temperature preference peak of 22.1[o]C in this assay.
Dgatu/DgEP2241 larvae raised at 25[o]C show a strong temperature preference that peaks at 17.6[o]C on a linear thermal gradient ranging from 12[0] to 35[o]C.
Homozygotes have a weakly penetrant posterior crossvein defect. Frequent branching of the crossvein is seen, either alone, or in combination in a "gapped" phenotype (where the crossvein is detached from either vein L4 or L5, but not both).
The "EP(2)2241" line was originally homozygous lethal in stock, but outcrossing yields homozygous viable lines.
