Regulated shuttling of the histone deacetylase HDAC5 to the nucleus may put a brake on cocaine addiction.
The histone deacetylase HDAC5 has been shown to regulate behavioral adaptations to cocaine. In this issue of Neuron, Taniguchi et al. (2012) describe a cAMP-dependent signaling pathway that regulates nuclear accumulation of HDAC5, suggesting a mechanism to couple cocaine with changes in HDAC5 function.
