TAK-243 (MLN7243) is a first-in-class, selective ubiquitin activating enzyme, UAE (UBA1) inhibitor (IC50=1 nM), which blocks ubiquitin conjugation, disrupting monoubiquitin signaling as well as global protein ubiquitination. TAK-243 (MLN7243) induces endoplasmic reticulum (ER) stress, abrogates NF-κB pathway activation and promotes apoptosis.

    Customer Validation
     TAK-243/Spautin-1 groups results consistently support a positive correlation between the activity of HSP90, ubiquitination, and proteasome system with the disassembly of NSGs.

     Left: immunoblot analysis assessing JAK1 expression in Myc-CaP cells that received knockout of Jak1 (Jak1 KO). Cells receiving nontargeting sgRNA were used as control. Right: surface expression of MHC-I measured by flow cytometry in the indicated cells treated with or without 50 nmol/L TAK-243 and stimulated with or without IFN-γ. Data were acquired from technical triplicates, representative of two independent experiments.

    Customer Validation
     The E1 inhibitor decreased the flux of ER-phagy in mCherry-GFP-FAM134B-WT cells induced with Torin 1. ER-phagy flux was quantified as the ratio between mCherry+/GFP– and mCherry+/GFP+ puncta, quantified using CQ1 software. Data are means ± s.d. of n = 5 independent experiments in which the number of cells per condition were: (DMSO) 837 basal, 1072 BafA1, 1038 Torin1, 966 BafA1+Torin1. Number of cells (10 µM TAK243): 729 basal, 1174 BafA1, 1060 Torin1, 1121 Torin1+BafA1

    Customer Validation
     Cells were treated with DMSO (control) or 10 µM TAK243 for 1, 2 and 4 h before TUBE-2 pulldown assays. Endogenous ubiquitination of FAM134B was detected by western blot (n = 1 experiment). The results showed that TAK243, a potent inhibitor of the ubiquitin (Ub)-activating enzyme, abolished endogenous FAM134B ubiquitination.
