The N terminal PH domain has been mutated to carry the W104A amino acid substitution.
dosW104A.hs.2sev.GFP fails to rescue dosP115
dosW104A.hs.2sev.GFP fails to rescue dosR31
The addition of dosW104A.hs.T:Avic\GFP to dosR31 homozygotes or dosP115/dosR31 flies fails to produce viable flies. The addition of dosW104A.hs.T:Avic\GFP to dosR31 or dosP115 homozygotes or dosP115/dosR31 flies leads to pharate lethality. Escapers show defects in eye morphology and in wing vein formation.
