Web8 dec. 2024 · Huntington's disease results from expansion of a glutamine-coding CAG tract in the huntingtin (HTT) gene, producing an aberrantly functioning form of HTT. … Weblength huntingtin structure is largely -helical, consisting of three major domains: the N-terminal domain, the bridge domain and the C-terminal domain. The N- and the C-terminal domains fold mainly in HEAT repeats, modules of alpha helix pairs connected by short loops [25]. Arrays of HEAT repeats form rod-like helical structures and appear to
