Description
Rabbit polyclonal to Histone H3 (tri methyl K4) - ChIP Grade
Specificity
ab8580 detects a 17 kDa band in Western Blot which is completely blocked by addition of Histone H3 tri methyl K4 peptide. Partial blocking is observed with addition of Histone H3 di methyl K4 peptide. We recommend determining optimal dilutions/concentrations for peptide blocking studies. Modification specificity is determined by Peptide Array. ab8580 binds strongly to Histone H3 tri methyl K4, and partially to Histone H3 di methyl K4 peptides. Minimal reactivity is observed with mono methyl K4, unmodified, mono, di or tri methyl K9 or mono, di or tri methyl K27 peptides (please see data below). This antibody reacts with tri methylated K4 within a sequence found in all mammals and a wide range of other species, including S. cerevisiae, S. pombe, N. crassa, Aspergillus nidulans, D. melanogaster, S. ocellaris, C. reinhardtii, C. elegans, Arabidopsis thaliana, Chicken, Xenopus, Zebrafish and Tobacco. The antibody will react with any species where the modification is present.

Primary antibody notes
In immunofluorescence, a distinct property of tri methyl lysine 4 is its apparent 'ringing' of regions that appear as nucleoplasmic 'holes'. These represent the positions of splicing factor compartments, which often are easy to identify using only DNA stains in Indian muntjac fibroblasts. These splicing factor compartments are known to be preferentially associated with active genes and highly acetylated histone H3. The antibody, as expected, fails to stain heterochromatin (work by Kirk McManus, lab of Michael Hendzel). The immunofluorescence results suggest this antibody is an exceptional euchromatin probe.

Target
Function
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
Sequence similarities
Belongs to the histone H3 family.
Developmental stage
Expressed during S phase, then expression strongly decreases as cell division slows down during the process of differentiation.
Post-translational
modifications
Acetylation is generally linked to gene activation. Acetylation on Lys-10 (H3K9ac) impairs methylation at Arg-9 (H3R8me2s). Acetylation on Lys-19 (H3K18ac) and Lys-24 (H3K24ac) favors methylation at Arg-18 (H3R17me).
Citrullination at Arg-9 (H3R8ci) and/or Arg-18 (H3R17ci) by PADI4 impairs methylation and represses transcription.
Asymmetric dimethylation at Arg-18 (H3R17me2a) by CARM1 is linked to gene activation. Symmetric dimethylation at Arg-9 (H3R8me2s) by PRMT5 is linked to gene repression. Asymmetric dimethylation at Arg-3 (H3R2me2a) by PRMT6 is linked to gene repression and is mutually exclusive with H3 Lys-5 methylation (H3K4me2 and H3K4me3). H3R2me2a is present at the 3' of genes regardless of their transcription state and is enriched on inactive promoters, while it is absent on active promoters.
Methylation at Lys-5 (H3K4me), Lys-37 (H3K36me) and Lys-80 (H3K79me) are linked to gene activation. Methylation at Lys-5 (H3K4me) facilitates subsequent acetylation of H3 and H4. Methylation at Lys-80 (H3K79me) is associated with DNA double-strand break (DSB) responses and is a specific target for TP53BP1. Methylation at Lys-10 (H3K9me) and Lys-28 (H3K27me) are linked to gene repression. Methylation at Lys-10 (H3K9me) is a specific target for HP1 proteins (CBX1, CBX3 and CBX5) and prevents subsequent phosphorylation at Ser-11 (H3S10ph) and acetylation of H3 and H4. Methylation at Lys-5 (H3K4me) and Lys-80 (H3K79me) require preliminary monoubiquitination of H2B at 'Lys-120'. Methylation at Lys-10 (H3K9me) and Lys-28 (H3K27me) are enriched in inactive X chromosome chromatin.
Phosphorylated at Thr-4 (H3T3ph) by GSG2/haspin during prophase and dephosphorylated during anaphase. Phosphorylation at Ser-11 (H3S10ph) by AURKB is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. In addition phosphorylation at Ser-11 (H3S10ph) by RPS6KA4 and RPS6KA5 is important during interphase because it enables the transcription of genes following external stimulation, like mitogens, stress, growth factors or UV irradiation and result in the activation of genes, such as c-fos and c-jun. Phosphorylation at Ser-11 (H3S10ph), which is linked to gene activation, prevents methylation at Lys-10 (H3K9me) but facilitates acetylation of H3 and H4. Phosphorylation at Ser-11 (H3S10ph) by AURKB mediates the dissociation of HP1 proteins (CBX1, CBX3 and CBX5) from heterochromatin. Phosphorylation at Ser-11 (H3S10ph) is also an essential regulatory mechanism for neoplastic cell transformation. Phosphorylated at Ser-29 (H3S28ph) by MLTK isoform 1, RPS6KA5 or AURKB during mitosis or upon ultraviolet B irradiation. Phosphorylation at Thr-7 (H3T6ph) by PRKCBB is a specific tag for epigenetic transcriptional activation that prevents demethylation of Lys-5 (H3K4me) by LSD1/KDM1A. At centromeres, specifically phosphorylated at Thr-12 (H3T11ph) from prophase to early anaphase, by DAPK3 and PKN1. Phosphorylation at Thr-12 (H3T11ph) by PKN1 is a specific tag for epigenetic transcriptional activation that promotes demethylation of Lys-10 (H3K9me) by KDM4C/JMJD2C. Phosphorylation at Tyr-42 (H3Y41ph) by JAK2 promotes exclusion of CBX5 (HP1 alpha) from chromatin.
Monoubiquitinated by RAG1 in lymphoid cells, monoubiquitination is required for V(D)J recombination (By similarity). Ubiquitinated by the CUL4-DDB-RBX1 complex in response to ultraviolet irradiation. This may weaken the interaction between histones and DNA and facilitate DNA accessibility to repair proteins.

ChIP - Histone H3 (tri methyl K4) antibody - ChIP Grade (ab8580)
Chromatin was prepared from U2OS cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 µg of chromatin, 2 µg of ab8580 (blue), and 20 µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach). Primers and probes are located in the first kb of the transcribed region.
Peptide Array - Histone H3 (tri methyl K4) antibody - ChIP Grade (ab8580)
All batches of ab8580 are tested in Peptide Array against peptides to different Histone H3 modifications. Six dilutions of each peptide are printed on to the Peptide Array in triplicate and results are averaged before being plotted on to a graph. Results show strong binding to Histone H3 - tri methyl K4 peptide (ab1342), indicating that this antibody specifically recognises the Histone H3 - tri methyl K4 modification.

Protein resolved on 15% SDS-PAGE gel. After transfer to PVDF membrane, blots were blocked in 1X PBS, 0.1% Tween-20, and 5% milk. ab1791 was diluted in 5 ml blocking buffer at 1/5000. Blots plus primary antibodies were either incubated overnight at 4C or at RT for 2 hr. Blots were washed 6X for 10 min each in PBS with 0.1% Tween-20 before addition of secondary antibodies. Secondary antibodies were diluted 1/2,000 in blocking buffer and incubated with blots for 2 hr at RT. Secondary blots were washed 4X for 10 min each in PBS with 0.1% Tween-20 and 2X for 10 min each in PBS.
