A hallmark of small ubiquitin-related modifier (SUMO) is the production of a C-terminal tail containing diglycines (GGs), which are believed to be required for SUMOylation. Whether GGs are required components in SUMOylation remains unanswered experimentally. In this study we found

Protein aggregation and its pathological effects are the major cause of several neurodegenerative diseases. In Huntington's disease an elongated stretch of polyglutamines within the protein Huntingtin leads to increased aggregation propensity. This induces cellular defects, culminating in neuronal loss, but
