Comments
  • FUNCTION: Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Required for appropriate cellular patterning in the root epidermis. Histone deacetylases act via the formation of large multiprotein complexes (By similarity).
  • CATALYTIC ACTIVITY: Hydrolysis of an N6-acetyl-lysine residue of a histone to yield a deacetylated histone.
  • SUBCELLULAR LOCATION: Nucleus (By similarity).
  • MISCELLANEOUS: HDA5, a tandem duplication of HDA18, is not required for the cellular patterning in the root epidermis.
  • SIMILARITY: Belongs to the histone deacetylase family. Type 2 subfamily.
  • SEQUENCE CAUTION:
    • Sequence=BAB10370.1; Type=Erroneous gene model prediction;
