Alternate Names for Histone H3 [ac Lys9] Antibody

  • H3 histone, family 3A
  • H3.3AH3F3H3F3B
  • H3.3B

Acetylation of histone H3 at the K9 residue is associated with chromosome condensation in mitotic cells. The presence of H3K9ac is correlated to H3K4 trimethylation, and their distribution is related to developmentally repressed genes in some species. It has been shown that neuron depolarization promotes intragenic histone acetylation leading toward the formation of this modification. In pituitary, dopamine receptor agonists lead toward apoptosis. However, in tumors, decreased availability and activity of these agonists, combined with decreased H3K9ac leads toward resistance to chemotherapies and cancer survival and proliferation. Nuclear receptor PPAR ' induces the enrichment of H3K9ac enrichment on downstream promoters, which has effects on transcription and ultimately nuclear receptor transactivation.
