Imprecise excision of the progenitor insertion, resulting in deletion of most of the Mesh1 transcription unit.
Mutant flies are susceptible to amino acid starvation compared to controls. Mutant larvae show reduced BrdU incorporation in the fat body under amino acid starvation compared to control larvae, although they show normal levels of BrdU incorporation under "fed" conditions.
Mesh15A3 is rescued by Scer\GAL4da.G32/Mesh1UAS.Tag:HA
Expression of Mesh1Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4da.G32 rescues the retarded body growth and susceptibility to amino acid starvation that is seen in Mesh15A3 animals.
