NDs are commonly manifested by protein aggregates, which exert harmful effects on proteostasis. Interestingly, it has been observed that AMPylation of heat shock proteins (HSPs) can maintain proteostasis by inhibiting the formation of protein aggregates. As previous studies only indicate that HSPs could regulate proteostasis, such a novel discovery further demonstrates the involvement of HSP70 AMPylation in the regulation of protein aggregation and the maintenance of proteostasis. Therefore, AMPylation can be considered to possess a therapeutic potential to target certain physiological processes related to proteostasis, such as age-related diseases.展开更多
