Huntingtin has a membrane association signal that can modulate huntingtin aggregation, nuclear entry and toxicity.


Huntington's disease is caused by an expanded polyglutamine tract in huntingtin protein, leading to accumulation of huntingtin in the nuclei of striatal neurons. The 18 amino-acid amino-terminus of huntingtin is an amphipathic alpha helical membrane-binding domain that can reversibly target to vesicles and the endoplasmic reticulum (ER). The association of… (More)
