Description
IU1 is a cell-permeable, reversible and selective inhibitor of human with of 4.7 μ M, 25-fold selective to IsoT. IU1 induces .
In vitro
IU1 binds specifically to the activated form of USP14. IU1 can potentially inhibit USP14 by preventing its docking on the proteasome, exhibiting little or no activity toward 8 other DUBs, IsoT, UCH37, BAP1, UCH-L1, UCH-L3, USP15, USP2, USP7. USP14 inhibition is rapidly established upon addition of IU1 and rapidly reversed upon its removal. IU1 inhibits USP14 induced chain trimming and decreases electrophoretic mobility of Ub-CCNB species. IU1 enhances proteasomal degradation of Ub-CCNB in the presence of USP14. IU1 promots degradation of tau and depletes TDP-43, ATXN3, and glial fibrillary acidic protein (GFAP) in proteotoxic mechanisms.
