USP19 activates HTT. 5 / 5
| 5

reach
"The major finding of this work is that cytoplasmic USP19 can promote aggregation of the polyQ expanded Atx3 and Htt proteins by up-regulating their protein levels."

reach
"Based on these lines of evidence, we propose a model for triage decision of the Htt protein modulated by USP19 through HSP90."

reach
"A mechanism of auto-inhibition of USP19 and activation by HSP90 is proposed, on which USP19 modulates the protein level of polyQ expanded huntingtin in cells."

reach
"Cytoplasmic Ubiquitin Specific Protease 19 (USP19) Modulates Aggregation of Polyglutamine Expanded Ataxin-3 and Huntingtin through the HSP90 Chaperone."

reach
"Our previous study has demonstrated that cytoplasmic ubiquitin specific protease 19 (USP19), through interacting with HSP90, up-regulates the protein levels of the N-terminal 552-residue fragments of Htt (Htt-N552) with normal and expanded polyQ, and consequently increases the aggregates formed by polyQ expanded Htt-N552 31."
