      • H3 histone, family 3A
      Background InformationHistone H3 is a 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.

      Key Applications
      • Dot Blot
      • Peptide Inhibition Assay
      • Western Blotting
      Application NotesPeptide Inhibition Analysis:
      10 μM of a Histone H3 peptide containing trimethyl-lysine 9 abolished detection of Histone H3 by anti-trimethyl Histone H3 (Lys9) in western blot analysis of HeLa acid extracts (Figure B, lane 4). Slight signal reduction was observed with 10 μM of a Histone H3 peptide containing dimethyl-lysine 9.

      Peptide Dot Blot Analysis:
      A 1:2000 dilution of a previous lot was incubated with serial dilutions of Histone H3 peptides containing various modifications spotted onto PVDF. Slight cross-reactivity with Histone H3 peptide containing dimethyl-lysine 9 was detected.

      Beadlyte® Histone Peptide Assay:
      1:2000-1:6000 dilutions of a previous lot were incubated with Histone H3 peptides containing various modifications conjugated to Luminex® microspheres. Slight cross-reactivity with Histone H3 peptides containing dimethyl-lysine 9 and trimethyl-lysine 27 was detected.

      Entrez Gene Number
      Entrez Gene SummaryHistones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene contains introns and its mRNA is polyadenylated, unlike most histone genes. The protein encoded is a replication-independent member of the histone H3 family.

      UniProt Number
      UniProt SummaryFUNCTION: 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.
      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.
