dawaact1 contains a 2.5kb deletion, including the second promoter, the start codon, and most of the coding sequence.
A small number of dawaact1 mutants survive till adulthood (i.e ~5%). Those that do survive exhibit normal-sized wings compared to those of heterozygous animals. They are fertile, but most of the progeny die and exhibit daw mutant phenotype.
dawaact1 mutants are not embryonic lethal and do not show obvious abnormalities in mesodermal tissues. Most dawaact1 mutant animals die during larval development. Mutant larvae exhibit the bloated anal pad phenotype of babo mutants.
dawaact1 has partially lethal - majority die | larval stage phenotype, non-suppressible by ActβCM.UAS/Scer\GAL4386Y
dawaact1 has partially lethal - majority die | larval stage phenotype, non-suppressible by baboQ302D.UAS/Scer\GAL4386Y
Expression of ActβCM.Scer\UAS in a dawaact1 background under the control of the neurosecretory driver Scer\GAL4386Y fails to suppress dawaact1 lethality.
Expression of baboQ302D.Scer\UAS in a dawaact1 background under the control of the neurosecretory driver Scer\GAL4386Y fails to suppress dawaact1 lethality.

dawaact1 mutant animals can be rescued by ubiquitous expression of dawScer\UAS.cGa using Scer\GAL4da.G32 and Scer\GAL4hs.PB-Ubi (to 66% and 56% of wild-type, respectively).
Expression of dawScer\UAS.cGa using the neurosecretory driver Scer\GAL4386Y rescues the anal pad phenotype of dawaact1 mutants, with approximately 89% of the expected homozygous animals surviving to become fertile adults.
Expression of dawScer\UAS.cGa using the Scer\GAL4phm.PO driver, to localise expression to the prothoracic portion of the ring gland, results in rescue of lethality of 84% of dawaact1 mutants.
