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.

A set of protein subcomplexes involved in PROTEIN SORTING of UBIQUITINATED PROTEINS into intraluminal vesicles of MULTIVESICULAR BODIES and in membrane scission during formation of intraluminal vesicles, during the final step of CYTOKINESIS, and during the budding of enveloped viruses. The ESCRT machinery is comprised of the protein products of Class E vacuolar protein sorting genes.
The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
A highly-conserved AAA ATPase that functions in the biogenesis of the transitional ENDOPLASMIC RETICULUM and fragmentation and reassembly of the GOLGI APPARATUS during MITOSIS. It also functions in a complex with UFD1L and NPLOC4 proteins to export misfolded ubiquitinated proteins from the endoplasmic reticulum and outer mitochondrial membrane to the cytoplasm for degradation by the PROTEASOME and also plays a role in AUTOPHAGY of ubiquitinated proteins. It occurs in neuronal INCLUSION BODIES from patients with AMYOTROPHIC LATERAL SCLEROSIS and LEWY BODIES from PARKINSON DISEASE patients.
A subtype of tetraspanin protein that plays a role in cell adhesion, cell motility, and tumor metastasis. It functions in platelet activation and aggregation, the formation of paranodal junctions in neuronal tissue, and the fusion of sperm with egg.
