TDP-43 is a nucleic acid binding protein, whose insoluble aggregates are neuropathological hallmarks of specific subsets of patients with amyotrophic lateral sclerosis and frontotemporal lobar degeneration. Post-translational modifications and acetylation of TDP-43 impact its interaction with RNA, its localization in the cells, and are linked to disease. Using antibodies generated against TDP-43 lysine acetylation sites, sirtuin-1 was found to potently deacetylate amber suppressed [acK136]TDP-43 and reduce its aggregation propensity. Thus, distinct lysine acetylations modulate nuclear import, RNA binding as well as phase separation and aggregation of TDP-43, suggesting regulatory mechanisms for TDP-43 pathogenesis.
