D217A mutation is within the catalytic domain.
When tlkdead.Scer\UAS is driven by Scer\GAL4ey.PH a massive reduction in head and eye structures is seen, creating a 'pin-head' phenotype. When tlkdead.Scer\UAS is expressed at low enough levels (using Scer\GAL4hs.2sev) for the animals to survive to adulthood, the only phenotype seen is greatly reduced larval salivary glands. Animals with salivary glands can only be grown at 18oC.
Scer\GAL4ey.PH, Tlkdead.UAS has head phenotype, suppressible by asf1UAS.cMa
Scer\GAL4ey.PH, Tlkdead.UAS has eye phenotype, suppressible by asf1UAS.cMa
The pin-head phenotype seen in tlkdead.Scer\UAS, Scer\GAL4ey.PH mutants is significantly suppressed by co-expression of asf1Scer\UAS.cMa.
