| Background Information | Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the beads on a string structure. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine. Dimethylation of Lys79 on histone H3 is associated with active gene transcription and is a marker for euchromatin. Histone H3 is methylated on Lys79 by the histone methyltransferase Dot1L.. |

| Application Notes | Chromatin Immunoprecipitation: Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using either 4 µL of Negative Control Supernatant, or 4 µL of Anti-dimethyl-Histone H3 (Lys79) and the Magna ChIP™ A Kit (Cat. # 17-610). Successful immunoprecipitation of dimethyl-Histone H3 (Lys79) associated DNA fragments was verified by qPCR using Control Primers Please refer to the EZ-Magna ChIP™ A (Cat. # 17-408) or EZ-ChIP™ (Cat. # 17-371) protocol for experimental details. Chromatin Immunoprecipitation: A representative lot of this antibody has been shown by an independent laboratory to work in ChIP. ChIP-Seq Analysis: A representative lot of this antibody was used by an independent laboratory for ChIP-Seq. See Egelhofer, T.A., et al. (2011). See Easwaran, H., et al. (2012).See Suzuki, H., et al. (2011). Dot Blotting: Specificity of a representative lot confirmed by the ability of a 1:2500 dilution of the antibody to recognize peptides corresponding to regions of histone H3 with various modifications Dot Blot Analysis: Absurance Histone H3 Antibody Specificity Array (Cat. No. 16-667) and Absurance Histone H2A, H2B, H4 Antibody Specificity Array (Cat. No. 16-665), which contain histone peptides with various modifications were probed with Cat. No 04-835-S, Anti-dimethyl Histone H3 (Lys79) Antibody, clone NL59 (1:500 dilution). Proteins were visualized using a Donkey anti-rabbit IgG conjugated to HRP and a chemiluminescence detection system. |

| Entrez Gene Number |
|
| Entrez Gene Summary | Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. |

| UniProt Summary | FUNCTION: SwissProt: Q16695 # 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. SIZE: 136 amino acids; 15508 Da SUBUNIT: The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA. SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Expressed in testicular cells. DEVELOPMENTAL STAGE: Expressed during S phase, then expression strongly decreases as cell division slows down during the process of differentiation. PTM: Acetylation is generally linked to gene activation. Acetylation on Lys-10 impairs methylation at Arg-9. Acetylation on Lys-19 and Lys-24 favors methylation at Arg-18 (By similarity). & Citrullination at Arg-9 and/or Arg-18 by PADI4 impairs methylation and represses transcription (By similarity). & Asymmetric dimethylation at Arg-18 by CARM1 is linked to gene activation. Symmetric dimethylation at Arg-9 by PRMT5 is linked to gene repression (By similarity). & Methylation at Lys-5, Lys-37 and Lys-80 are linked to gene activation. Methylation at Lys-5 facilitates subsequent acetylation of H3 and H4. Methylation at Lys-80 is associated with DNA double-strand break (DSB) responses and is a specific target for TP53BP1. Methylation at Lys-10 and Lys-28 are linked to gene repression. Methylation at Lys-10 is a specific target for HP1 proteins (CBX1, CBX3 and CBX5) and prevents subsequent phosphorylation at Ser-11 and acetylation of H3 and H4. Methylation at Lys-5 and Lys-80 require preliminary monoubiquitination of H2B at Lys-120. Methylation at Lys-10 and Lys-28 are enriched in inactive X chromosome chromatin (By similarity). & Phosphorylated at Thr-4 by GSG2/haspin during prophase and dephosphorylated during anaphase. At centromeres, specifically phosphorylated at Thr-12 from prophase to early anaphase. Phosphorylated at Ser-11 during the whole mitosis. Phosphorylation at Ser-11, which is linked to gene activation, prevents methylation at Lys-10 but facilitates acetylation of H3 and H4. Phosphorylated at Ser-29 by MLTK isoform 1, RPS6KA5 or AURKB during mitosis or upon ultraviolet B irradiation (By similarity). & Phosphorylation at Ser-11 is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. In addition phosphorylation at Ser-11 is important during interphase because it enables the transcription of genes following external stimulation, like stress or growth factors. Phosphorylation at Ser-11 is also an essential regulatory mechanism for neoplastic cell transformation. Phosphorylation at Ser-11 by AURKB/Aurora-B mediates the dissociation of HP1 proteins (CBX1, CBX3 and CBX5) from heterochromatin. & Ubiquitinated (By similarity). SIMILARITY: SwissProt: Q16695 ## Belongs to the histone H3 family. |
