HDAC9 is a class IIa histone deacetylase with multiple isoforms. The longest isoform contains an N-terminal regulatory domain with binding sites for transcription factors, a catalytic deacetylase domain, and a C-terminal domain. HDAC9 shuttles between nucleus and cytoplasm in response to cellular signals.
HDAC9 regulates gene expression by deacetylating histones and interacting with transcription factors. It is involved in stress responses, circadian rhythm, synaptic plasticity, and immune regulation. In neurons, HDAC9 modulates memory formation and response to neuronal activity. HDAC9 deficiency enhances learning and memory in mice.
