UAS regulatory sequences drive expression of a C-terminally truncated Abi consisting of only the N-terminal WAVE-binding (WAB) and homeodomain homologous region (HHR) domains.
Scer\GAL4da.G32/AbiWAB-HHR.UAS rescues AbiΔ20
Scer\GAL4elav-C155/AbiWAB-HHR.UAS rescues AbiΔ20
Ubiquitous expression of AbiWAB-HHR.Scer\UAS under the control of Scer\GAL4da.G32 completely rescues the lethality of AbiΔ20 mutants.
