Figure Legend Snippet: KMT5A induces mono-methylation of lysine 193 on IRF3 (A) HEK293T cells were transfected with FLAG-IRF3 and/or HA-KMT5A plasmids. Whole-cell lysates were collected, followed by IP using anti-FLAG magnetic beads. Subsequent analysis was conducted via IB. (B) Whole-cell lysates were extracted from RKO cells with either control (shNC) or KMT5A shRNA (#1 and #2) silencing. IP was performed using anti-IRF3 antibodies, followed by WB analysis. (C) RKO cells were transfected with HA-KMT5A WT or HA-KMT5A D338A, IP was performed using anti-IRF3 antibodies, followed by WB analysis. (D) RKO cells were treated with either DMSO or UNC0379. IP was performed using anti-IRF3 antibodies, followed by IB analysis. (E) RKO cells were treated with either DMSO or varying concentrations of UNC0379. IP was conducted using anti-IRF3 antibodies, followed by IB analysis. (F) The levels of IFN-β in RKO cells from experiment (E) were quantified using ELISA. Data were analyzed using one-way ANOVA with Tukey’s post-hoc test, presented as mean ± SD. Statistical significance was defined as ∗∗∗ p < 0.001 and ∗∗∗∗ p < 0.0001. (G) In vitro methylation assays were conducted by incubating purified His-IRF3 with KMT5A in the presence of S-adenosyl-L-methionine, followed by IB analysis. (H) Secondary mass spectrometry results of IRF3 K193 methylation were obtained. (I) HEK293T cells were transfected with FLAG-IRF3 wild-type or mutant plasmids, followed by transfection with either a vector or HA-KMT5A. Whole-cell lysates were collected, and IP was performed using anti-FLAG magnetic beads, followed by IB analysis. (J) Amino acid sequences at the K193 site of IRF3 were compared across different species. All immunoblotting experiments were conducted independently in triplicate, yielding consistent results.

Figure Legend Snippet: KMT5A hindering production of IFN-β depends on IRF3 K193 methylation (A) HEK293T cells were transfected with vector, FLAG-IRF3 wild-type, or K193R mutant plasmids. Whole-cell lysates were collected, followed by IP using anti-FLAG magnetic beads, and subsequent analysis was performed via IB. (B) KMT5A-knockout RKO cells were transfected with FLAG-IRF3 wild-type or K193R mutant plasmids. The cells were treated with poly(I) or UNC0379, then whole-cell lysates were collected, and IP was conducted using anti-FLAG magnetic beads, followed by IB analysis. (C) RKO cells from experiment (B) were co-transfected with reporter plasmids IFN-β-Luc and pRL-TK. After 24 h, the cells were harvested, and luciferase activity was measured using a dual-luciferase reporter assay kit. (D) The relative mRNA levels of INF-β in RKO cells from experiment (B) were quantified using qPCR. (E) KMT5A knockout RKO cells were transfected with HA-KMT5A and FLAG-IRF3 wild-type or K193R mutant plasmids. Whole-cell lysates were collected, followed by IP using anti-FLAG magnetic beads, and subsequent IB analysis was performed. (F) Relative quantification of phosphorylated IRF3 (p-IRF3) protein was conducted in experiment (E). (G) The relative mRNA levels of INF-β in RKO cells from experiment F were quantified using qPCR. (C) and (D) were analyzed using one-way ANOVA with Tukey’s post-hoc test, with data presented as mean ± SD. (F) and (G) were analyzed using two-way ANOVA with Tukey’s post-hoc test. Statistical significance was defined as ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001, while ns indicates no statistical difference. All immunoblotting experiments were performed independently in triplicate, yielding consistent results.
