Several other neurological diseases also result from the expansion of polyglutamine regions in different proteins. Despite intense efforts, no definitive biochemical or physiological role for huntingtin has been described, nor has a function been assigned to the polyglutamine region in unaffected individuals. This article presents the hypothesis that polyglutamine expansions within huntingtin and other polyglutamine proteins provide a function in and of themselves. Incorporating multiple glutamine residues into a protein during synthesis, and releasing them during protein turnover, may represent a means of minimizing interruptions in brain levels of glutamine and glutamate during periods of malnutrition. The number and variety of different proteins containing polyglutamine expansions can be interpreted as a series of evolutionary \u201cexperiments\u201d toward a nontoxic form for glutamine storage.<\/jats:p>","DOI":"10.1177\/1073858406289639","type":"journal-article","created":{"date-parts":[[2006,7,13]],"date-time":"2006-07-13T15:42:47Z","timestamp":1152805367000},"page":"300-304","source":"Crossref","is-referenced-by-count":7,"title":["Is Huntington's a Glutamine Storage Disease?"],"prefix":"10.1177","volume":"12","author":[{"given":"William S.
