HDAC5 physically interacts with MEF2A in vivo and in vitro and strongly inhibits its transcriptional activity. The repression is independent of the HDAC5 deacetylase domain; the N-terminal non-deacetylase domain is sufficient for repression. The MADS box/MEF2-domain region of MEF2A interacts with a limited region in the N-terminal part of HDAC5. |

Transgenic expression of a signal-resistant (phosphorylation-defective) HDAC5 in mouse heart causes loss of cardiac mitochondria, down-regulation of mitochondrial enzymes, and down-regulation of PGC-1α, placing HDAC5 as a repressor of the MEF2/PGC-1α axis controlling cardiac mitochondrial biogenesis. |
