Egfrk05115 mutants exhibit defects in terminal cell lumenogenesis, with terminal cells lacking a visible gas-filled lumen and exhibiting some branching defects. Only a small percentage (approximately 15%) of Egfrk05115 mutant terminal cells exhibit defective lumen.
Homozygous clones in the eye disc grow poorly and are very small.
Heterozygotes show a direct effect on the shape of the wing.
Malpighian tubules are very reduced in mutant embryos. Midgut constrictions do not form. There is a failure in germ band retraction and dorsal closure. Salivary glands are short. No head epithelium is present.
Egfr[+]/Egfrk05115 is a non-suppressor of lethal phenotype of Uba1B1/Uba1B2
Egfr[+]/Egfrk05115 is an enhancer of dorsal appendage phenotype of Ras85Dix12a
Egfr[+]/Egfrk05115 is a suppressor of embryonic/larval tracheal system phenotype of Ptp10D1, Ptp4E1
A Egfrk05115/+ background does not suppress the ectopic cell divisions found in Uba1B1/Uba1B2 trans-heterozygous eye discs.
Strong dominant enhancer of the Ras85Dix12a eggshell phenotype; 0-20% of dorsal appendages are wild type.
