A Scheme for the disruption of the YAP-B-MYB interaction by MY-COMP. B HeLa cells were stably transfected with expression constructs for inducible MY-COMP or MY-COMP (2–79). Cell lines were treated with the indicated dose of doxycycline and the expression of MY-COMP was analyzed by immunoblotting with an anti-HA antibody. Actin served as a loading control. C HeLa cells were transfected with the indicated expression constructs. Flag-YAP was immunoprecipitated and bound HA-B-MYB was detected by immunoblotting. When MY-COMP was co-transfected, the interaction between flag-YAP and HA-B-MYB was decreased. Input: 3% of the lysate. D The expression of GFP or of the indicated MY-COMP constructs coupled to GFP through a T2A site was induced by doxycycline. FACS was performed to determine the percentage of in different phases of the cell cycle. GFP-positive cells (expressing MY-COMP) were analyzed. E Quantification of the results shown in D. Error bars indicate SDs. n = 3 independent replicates. Student’s t test. *p < 0.05, ns not significant.
