USP18 activates MAP3K7. 6 / 6
| 6

reach
"However, NEMO deficiency did not lead to loss of interaction between USP18 and TAK1 (XREF_FIG), suggesting that USP18 targets TAK1 complex and IKK complex by distinct mechanisms."

reach
"Based on our experimental data, we propose a working model to explain how USP18 negatively regulates NF-kappaB signaling by targeting TAK1 and NEMO."

reach
"USP18 negatively regulates NF-kappaB signaling by targeting TAK1 and NEMO for deubiquitination through distinct mechanisms."

reach
"Recent work has demonstrated that USP18 has the ability to deubiquitinate the transforming growth factor-activated kinase 1 (TAK1) complexes required for NF-κB activation in T cells and that overexpression of USP18 leads to decreased nuclear activation and impaired formation of TAK1 complexes (47)."

reach
"After TLR ligand stimulation, TAK1 and NEMO undergo K63 linked ubiquitination by TRAF6, while upregulated USP18 targets TAK1 and NEMO."

reach
"Considering the phenotypes observed with Tak -/- and Usp18 -/- T cells or Usp18 -/- T cells transfected with USP18 (WT) or USP18 (C61S), we further hypothesized that USP18 targets TAK1 complex and catalyzes deubiquitination of TAK1."
