WebBiological Activity CSN5i-3 is a potent and selective CSN5 (COP9 signalosome) inhibitor. It inhibits deneddylation of NEDD8-modifed CRLs (IC 50 = 5.8 nM), keeping them in the neddylated state, and leading to inactivation of a subset of CRLs by inducing degradation of their substrate receptor module (SRM). In A2780 ovarian cancer cells, CSN5i-3 down … WebJan 5, 2024 · CSN5 encodes a deubiquitinating enzyme that was found to deubiquitinate and stabilize PD-L1, resulting in enhanced PD-L1 expression in response to inflammatory TNFα signaling. Further, the CSN5 inhibitor curcumin blocked TNFα-induced PD-L1 stabilization in multiple cancer cell types.
