Examples of polyQ AR loss- and gain-of-function in SBMA. (A) Transcriptional dysregulation. The polyQ AR may activate expression of certain genes to a lesser (top) or greater (bottom) extent than the wt AR. (B) Altered protein interactions. The polyQ AR may fail to associate with proteins (top) or bind more strongly to proteins (bottom) that normally interact with the wt AR.
