Figure Lengend Snippet: Fig. 2 The interaction between USP46 and TRAF6. A and B Western blot analysis of TRAF6 expression in normal pneu- monocyte and lung cancer cell lines. C and D A549 cells were transfected with His-USP46 and Flag-TRAF6 in the indicated combinations. Immunoprecipi- tation was carried out to explore the interaction between USP46 and TRAF6

Figure Lengend Snippet: Fig. 3 USP46 inhibited the ubiquitination of TRAF6 and stabilized the expression of TRAF6. A Overexpression of USP46 affected the ubiquitina- tion of TRAF6. Cells in each group were treated with the proteasomal inhibitor MG132. Cell lysates were collected and subjected to immuno- precipitation with the anti- TRAF6 antibody. The levels of ubiquitin-conjugated TRAF6 were detected by Western blot. B Representative Western blot and relative expression of TRAF6 in a graph revealed that USP46 overexpression inhibits degeneration of TRAF6 protein in A549 cells

(B) Model demonstrating shared interface residues on TRAF6 for UL37 (predicted by Alphafold) and MAVS (PDB: 4Z8M) binding. (C) Schematic of experiments investigating UL37 suppression of MAVS signaling. 293T MAVSKO IFNB1-GLuc reporter cells induce Gaussia luciferase (GLuc) driven by tandem IFNB1 promoter elements after MAVS overexpression.
