At least nine inherited neurodegenerative diseases share a polyglutamine expansion in their respective disease proteins. These diseases show distinct neuropathological changes, suggesting that protein environment and protein-protein interactions play an important role in the specific neuropathology. ⋯ Recent studies have identified several huntingtin-interacting proteins that might be associated with the normal function of huntingtin and/or involved in the pathology of Huntington's disease. In this article, we focus on the potential roles of huntingtin-protein interactions in the pathogenesis of Huntington's disease.
