While class I HDACs are localized predominantly within the nucleus, class II HDACs shuttle into and out of the nucleus in response to intracellular signaling.
1 Class IIa HDACs, which includes HDAC4, 5, 7, and 9, commonly act as corepressors and play diverse roles in cell biology.
2 MC 1568 is a selective inhibitor of class IIa HDACs, with greater than 170-fold selectivity over class I HDACs, including HDAC1.
3,4,5 It has been used in cells (1-10 μM) and in mice to elucidate the roles of class IIa HDACs in cell proliferation and differentiation, apoptosis, myogenesis, adipogenesis, and fibrosis.
