  • FunctionResponsible 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. Histone deacetylases act via the formation of large multiprotein complexes. Deacetylates SP proteins, SP1 and SP3, and regulates their function. Component of the BRG1-RB1-HDAC1 complex, which negatively regulates the CREST-mediated transcription in resting neurons. Upon calcium stimulation, HDAC1 is released from the complex and CREBBP is recruited, which facilitates transcriptional activation. Deacetylates TSHZ3 and regulates its transcriptional repressor activity. Deacetylates 'Lys-310' in RELA and thereby inhibits the transcriptional activity of NF-kappa-B.
  • Tissue specificityUbiquitous, with higher levels in heart, pancreas and testis, and lower levels in kidney and brain.
  • Sequence similaritiesBelongs to the histone deacetylase family. HD type 1 subfamily.
  • Post-translational
    Sumoylated on Lys-444 and Lys-476; which promotes enzymatic activity. Desumoylated by SENP1.
    Phosphorylation on Ser-421 and Ser-423 promotes enzymatic activity and interactions with NuRD and SIN3 complexes.
    Ubiquitinated by CHFR, leading to its degradation by the proteasome.

  • ICC/IF image of ab33278 stained human MCF7 cells. The cells were methanol fixed (5 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab33278, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa, HEK 293 and HepG2 cells.

  • Immunohistochemistical detection of HDAC1 using antibody ab33278 on PFA perfusion fixed frozen rat heart sections. Primary antibody Dilution 1/300, Incubated for 18 hours @ 20°C in PBS + 0.3 % Triton X100. Secondary antibody: Goat anti-rabbit Alexa Fluor 488 (1/1000). The antibody produced some staining in the cytoplasm and what seems to be the nucleus of muscle cells in rat heart tissue. The tissues were fixed (animals perfused fixed) with 4% PFA and later postfixed overnight in the same fixative. They were cryoprotected in 30% sucrose and cut using a cryostat.
