タイトル USP10 Is a Driver of Ubiquitinated Protein Aggregation and Aggresome Formation to Inhibit Apoptosis.
ジャーナル iScience
Abstract Accumulation of ubiquitinated proteins is cytotoxic, but cells inactivate these cytotoxicities by inducing aggresome formation. We found that ubiquitin-specific protease 10 (USP10) inhibits ubiquitinated protein-induced apoptosis by inducing aggresome formation. USP10 interacted with the ubiquitin receptor p62 and the interaction augmented p62-dependent ubiquitinated protein aggregation and aggresome formation, thereby cooperatively inhibiting apoptosis. We provide evidence that USP10/p62-induced protein aggregates inhibit proteasome activity, which increases the amount of ubiquitinated proteins and promotes aggresome formation. USP10 induced aggresomes containing α-synuclein, a pathogenic protein in Parkinson disease, in cultured cells. In Parkinson disease brains, USP10 was colocalized with α-synuclein in the disease-linked aggresome-like inclusion Lewy bodies, suggesting that USP10 inhibits α-synuclein-induced neurotoxicity by promoting Lewy body formation. Collectively, these findings suggest that USP10 is a critical factor to control protein aggregation, aggresome formation, and cytotoxicity in protein-aggregation-related diseases.
