Mblk-1-binding motif analysis and luciferase assay. (A) Three Mblk-1-binding motifs identified with DREME. (B) Two Mblk-1-binding motifs identified with MEME. (C) pGL4.23 reporter vector construction used for the luciferase assay. (D) The results of the luciferase assay using reporter vectors containing motif 1: 6xGAGA or 6xGAGA with 4-bp spacer sequence (left panel) and motif 2: 6xGAAATTTT or motif 3: 6xATTTTGG sequence (right panel). Data represent means ± SD (n = 3). Significant differences are indicated by asterisks (*p < 0.05, **p < 0.01, ***p < 0.005, Tukey–Kramer test).
