Physical interaction of TBX5 with HDACs and functional consequences. (A) Pull-down assay showing the physical interaction between TBX5 and class I and class II HDACs. HDACs (1–5) interact with TBX5, whereas HDAC6 does not (IP: immunoprecipitation and IB: Immunoblot). Full-length blots are shown in Supplementary Fig. S1. (B,C) Luciferase-reporter assays showing that class I histone deacetylase HDAC1 and class II histone deacetylases HDAC4 and 5 repress TBX5-mediated transcriptional activity on the MYH6 promoter. Results are from three individual experiments. Error bars represent SD, *P < 0.02, **P < 0.01. Inset showing the Fold changes.
