Interestingly, Ataxin-10 (Atxn10) and Huntingtin-associated protein 1 (Hap1), proteins associated with the neurodegenerative disease spinocerebellar ataxia 10 (SCA10) and Huntington’s disease, respectively, were identified as UBQLN2 interactors. The gene discussed is UBQLN2; the disease is juvenile Huntington disease.
