Figure Legend Snippet: A. Western blots of total cell lysates for MM6 cells in suspension treated with puromycin and analyzed by WB with anti-puromycin antibody (to assess global protein synthesis) reveal that Ezrin does not influence global translation: RNAi knockdown to Ezrin (siEZR) did not show difference compared to luciferase (siLUC) control (left panel). In contrast, CRISPR 4E reduces global translation signal by about 50% relative to CRISPR-CTRL, consistent with previous studies.
