1 PolyQ-expanded huntingtin and ataxin-3 sequester ubiquitin adaptors hHR23B and UBQLN2 into aggregates via conjugated ubiquitin. polyglutamine RAD23 homolog B, nucleotide excision repair protein Homo sapiens
2 We found that polyQ-expanded Htt-N552 and Atx-3 sequester endogenous Ub adaptors, human RAD23 homolog B (hHR23B) and ubiquilin (UBQLN)-2, into inclusions. polyglutamine RAD23 homolog B, nucleotide excision repair protein Homo sapiens
3 Moreover, polyQ-expanded Htt-N552 and Atx-3 reduce the protein level of xeroderma pigmentosum group C (XPC) by sequestration of hHR23B, suggesting that this process may cut down the available quantity of hHR23B and thus affect its normal function in stabilizing XPC. polyglutamine RAD23 homolog B, nucleotide excision repair protein Homo sapiens
