• Product nameAnti-HDAC5 antibodySee all HDAC5 primary antibodies ...
  • Description
    Rabbit polyclonal to HDAC5
  • SpecificityThe antibody detects ~124 kDa histone deacetylase 5. It does not cross-react with other HDAC proteins including HDAC1, 2, 3, 4, 6, 7, and 8.
  • Tested applicationsIHC-FoFr, IHC-P, IP, WB more details
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic peptide corresponding to Human HDAC5.

  • EpitopeThe immunogen was a synthetic peptide surrounding amino acid 575 of human HDAC-5
  • Positive control
    • HeLa or COS cell lysate
  • General notesSome tissues may not express the HDAC-4 and 5 protein or it is expressed at extremely low amount. HDAC-1,2,3,6,7 are usually much more abundant (could be ~100X more) than HDAC-4 & 5. We would strongly suggest using positive control (HeLa lysate).



Our Abpromise guarantee covers the use of ab1439 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Notes
IHC-FoFr Use at an assay dependent dilution. PubMed: 19939859
IHC-P Use a concentration of 20 µg/ml.
IP Use a concentration of 20 µg/ml.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 121.9 kDa.
HDAC-5 is in very low abundance (~100X lower) in comparison to other HDACs (e.g., HDAC-1, 2, 6, or 7, etc.). For certain tissue and cells, it can be very difficult to detect due to the low abundance, we recommend to try to use strong lysis buffers (containing NP40),load more protein and use more antibody.


  • 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. Involved in muscle maturation by repressing transcription of myocyte enhancer MEF2C. During muscle differentiation, it shuttles into the cytoplasm, allowing the expression of myocyte enhancer factors.
  • Tissue specificityUbiquitous.
  • Sequence similaritiesBelongs to the histone deacetylase family. HD type 2 subfamily.
  • DomainThe nuclear export sequence mediates the shuttling between the nucleus and the cytoplasm.
  • Post-translational
    Phosphorylated by CaMK at Ser-259 and Ser-498. The phosphorylation is required for the export to the cytoplasm. Phosphorylated by the PKC kinases PKN1 and PKN2, impairing nuclear import.
    Ubiquitinated. Polyubiquitination however does not lead to its degradation.
  • Cellular localizationNucleus. Cytoplasm. Shuttles between the nucleus and the cytoplasm. In muscle cells, it shuttles into the cytoplasm during myocyte differentiation. The export to cytoplasm depends on the interaction with a 14-3-3 chaperone protein and is due to its phosphorylation at Ser-259 and Ser-498 by CaMK.
