The ubiquitin ligase UBR5 suppresses proteostasis collapse in pluripotent stem cells from Huntington’s disease patients

Induced pluripotent stem cells (iPSCs) suppress the aggregation of Huntington’s disease (HD) polyQ-expanded huntingtin (HTT). Here the authors show that proteasome activity determines the levels of mutant HTT in HD-iPSCs and find that UBR5 is a modulator of super-vigilant proteostasis of iPSCs.
