TAK-981 is potent and selective inhibitor of SUMO-activating enzyme (SAE; IC50 = <10 nM). SUMOylation is a reversible post-translational modification that regulates protein function by covalent attachment of small ubiquitin-like modifier (SUMO) proteins to a protein substrate. SUMOylation has a key role in restraining Type I interferon (IFN) responses. TAK-981 upregulates the expression of IFN-regulated genes in the blood and tumor tissue in an A20 syngeneic lymphoma mouse model. It also decreases intratumor levels of SUMOlyated proteins and reduces tumor growth in the same model.
