HDAC9 is located in the nucleus, expressed most highly in brain, heart, muscle, and testis. It is responsible for the deacetylation of lysine residues on the N-terminal region of the core histones (H2A, H2B, H3 and H4). The result of deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. HDAC9 represses MEF2-dependent transcription by recruiting HDAC1 and 3. It appears to inhibit skeletal myogenesis and be a factor in heart development. By repressing JUN transcription via HDAC1 and inhibiting JUN phosphorylation by MAPK10, HDAC9 protects neurons from apoptosis. Anti-HDAC9 therefore is ideal for investigators interested in Cardiovascular or Epigenetics and Nuclear Signaling research.
Anti-HDAC9 affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to the internal region of human HDAC9 protein.
