Fig. 4. The interaction between AMOTL1 and YAP1 protects each other from degradation.
a AMOTL1 prevented YAP1 from degradation in a dosage-dependent manner. b The half-life of YAP1 protein was elongated by AMOTL1 overexpression. c YAP1 degradation is mainly through ubiquitination, which was reduced by AMOTL1 overexpression in a dosage-dependent manner. d YAP1 also protected AMOTL1 from degradation dosage-dependently. e YAP1 prolonged the half-life of AMOTL1 protein. f YAP1 prevented AMOTL1 ubiquitination in a dosage-dependent manner. g The list of top ten genes that were downregulated in YAP1-depleted cells. CTGF was the top one. h Western blot analysis confirmed that both siAMOTL1 and siYAP1 suppressed CTGF expression, while AMOTL1 overexpression increased YAP1 and CTGF protein levels.
