"Recent studies have shown that USP4 serves as a critical control to downregulate NF-κB activation through deubiquitinating TAK1, TRAF2 and TRAF6. xref , xref It has also been reported that HDAC2 could inhibit NF-κB activation. xref , xref In our study we found that HDAC2 could reduce TNFα-induced acetylation of RelA in H1299 cells, but HDAC2 could not interact with RelA ( xref ), consistent with previous studies. xref Therefore, we explored the possibility that USP4 inhibits NF-κB transcriptional activity through HDAC2 using an NF-κB-dependent luciferase reporter gene assay."

"Studies focused on the other USPs demonstrated that USP14 overexpression regulates IkappaB polyubiquitination to stimulate its degradation 26, and ectopic expression of USP4 inhibits the TRAF2- and TRAF6 stimulated NF-kappaB reporter gene and negatively regulates the TNF-alpha-induced IkappaB-alpha degradation and NF-kappaB activation 27."
