UASt regulates expression of the antisense product of Hsap\JPH3 (termed 'HDL2') containing 138 CAG repeats, tagged with GFP at the N-terminus and Tag:NLS(Unk) at the C-terminus.
This variant is described relative to Hsap\JPH3 despite evidence that disease may be associated with an antisense ORF as the antisense ORF is not yet named.
