The HD domain (amino acids 232-291) has been deleted.
Unlike overexpression of wild-type eyg, expression of eygΔHD.Scer\UAS, under the control of Scer\GAL4dpp.blk1, does not cause extra ventral eye formation.
Scer\GAL4eyg-22-2/eygΔHD.UAS partially rescues eyg22-2/eygM3-12
Expression of eygΔHD.Scer\UAS in a eyg22-2/eygM3-12 background leads to partial rescue of the mutant eye and mutant thorax phenotypes.
