UASt sequences drive expression of a mutated dx (carries the amino acid replacements H570A and H573A) which has had amino acids 46 to 204, a N binding domain, removed. The coding sequence is tagged at the C-terminal end with Tag:GST.
Expression of dxΔPRM.Scer\UAS.T:Sjap\GST when driven by Scer\GAL4ptc-559.1 does not produce a noticeable effect.
