  • Description
    Sheep polyclonal to acetyl Lysine
  • Host species
  • Specificity
    The antibody has also been shown to react against histones, PCAF and E2F in Western blotting. Its suitability as a pan-specific anti-acetylated lysine antibody is currently under evaluation. Immunohistochemistry showed that the antiserum stains human and mouse chromosome preparations in a pattern that correlates with the acetylation as established by other means (unpublished data) and is equivalent to the rabbit polyclonal described in Turner & Fellows.

  • Relevance
    In the nucleus, DNA is tightly packed into nucleosomes generating an environment which is highly repressive towards DNA processes such as transcription. Acetylation of lysine residues within proteins has emerged as an important mechanism used by cells to overcome this repression. The acetylation of non-histone proteins such as transcription factors, as well as histones appears to be involved in this process. Acetylation may result in structural transitions as well as specific signaling within discrete chromatin domains. The role of acetylation in intracellular signaling has been inferred from the binding of acetylated peptides by the conserved bromodomain. Furthermore, recent findings suggest that bromodomain/acetylated-lysine recognition can serve as a regulatory mechanism in protein-protein interactions in numerous cellular processes such as chromatin remodeling and transcriptional activation. The reversible lysine acetylation of histones and non-histone proteins plays a vital role in the regulation of many cellular processes including chromatin dynamics and transcription, gene silencing, cell cycle progression, apoptosis, differentiation, DNA replication, DNA repair, nuclear import, and neuronal repression. More than 20 acetyltransferases and 18 deacetylases have been identified so far, but the mechanistic details of substrate selection and site specificity of these enzymes remain unclear. Over 40 transcription factors and 30 other nuclear, cytoplasmic, bacterial, and viral proteins have been shown to be acetylated in vivo.

Thank you for your enquiry. This antibody is currently under evaluation for its use as a pan-acetyl-lysine antibody. However, the immunogen used to raise this antibody was a tetra-acetylated synthetic N-terminal peptide, corresponding to amino acids 1-18 of Human histone H4. It has been shown to react against histones, PCAF and E2F. Given the latter two it is likely to recognise acetylated non-histone proteins. It has not been tested against yeast. However, given the conservation of the histone tails and the broad spectrum of specificity I consider this likely. Should you require further assistance, please do not hesitate to contact me.

We have not further tested the cross-reactivity of this antibody, all we can say is that it is likely to cross react with yeast based on sequence homology. I would expect it to work in yeast as there is a high level of histone homology between species.

We do not currently have monoclonals to the different isoforms, but expect to add these to the range soon. Abcam
