Figure Lengend Snippet: Enrichment and biotinylation of nuclear proteins in HEK293-tet-RhoA-TurboID (A) HEK293-tet-RhoA-TurboID were treated with tetracycline for 2 h followed by biotin for 20 min. The stably expressing TurboID was detected by western blotting with anti-HA antibody. The biotinylated proteins in samples from cell lysate and nuclear fraction (streptavidin pulldown) were analyzed by western blotting with Alexa Fluor™ 680 Streptavidin Conjugate. (B) Western blot of indicated proteins in total cell lysate and nuclear fraction (streptavidin pulldown). Nucleolin and β-tubulin were used as nuclear and cytosolic marker respectively. (C) Quantification shows the normalized YAP expression from B. Replicates=4. Values are means ± s.d. ∗∗∗∗ p < 0.0001.
