1 In spinal and bulbar muscular atrophy (SBMA), polyQ expansion within the androgen receptor (AR) causes progressive neuromuscular toxicity, the molecular basis of which is unclear. polyglutamine androgen receptor Mus musculus
2 In spinal and bulbar muscular atrophy (SBMA), polyQ expansion within the androgen receptor (AR) causes progressive neuromuscular toxicity, the molecular basis of which is unclear. polyglutamine androgen receptor Mus musculus
3 Using quantitative proteomics, we identified changes in the AR interactome caused by polyQ expansion. polyglutamine androgen receptor Mus musculus
4 We found that the deubiquitinase USP7 preferentially interacts with polyQ-expanded AR, and that lowering USP7 levels reduced mutant AR aggregation and cytotoxicity in cell models of SBMA. polyglutamine androgen receptor Mus musculus
