      Background InformationHistones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications, which include acetylation, phosphorylation, methylation, and ubiquitin-ation, occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Trimethylation of histone H4 on lys20 (H4-K20me3) selectively marks constitutive pericentromeric hetero-chromatin and imprinting control regions, while mono- and dimethylation are broadly distributed but principally enriched in euchromatin regions. Although the biological function of H4K20me remains poorly understood, studies suggest that H4-K20me2 is involved in the guidance of DNA repair proteins to DNA strand breaks, whereas H4K20me1 is associated with chromatin condensation processes. PR-Set7 (also known as SET8) specifically catalyzes monomethylation of H4K20me1.

      PresentationCultured supernantant in 0.05% sodium azide
      ApplicationUse Anti-monomethyl-Histone H4 (Lys20) Antibody, clone NL314 (rabbit monoclonal antibody) validated in WB, Mplex to detect monomethyl-Histone H4 (Lys20) also known as H4K20me1, Histone H4 (mono methyl K20).
      Key Applications
      • Western Blotting
      • Multiplexing
      Application NotesImmunoblot Analysis:
      A 1:4000 dilution of a previous lot detected methylated histone H3 in acid extracted proteins from HeLa cells. The antibody did not detect unmethylated recombinant Histone H3.

      Beadlyte® Histone-Peptide Specificity Assay: 1:2,000-1:30,000 dilutions of a previous lot were incubated with histone H4 peptides containing various modifications conjugated to Luminex® microspheres. Specificity to monomethyl-histone H4 (Lys20) was demonstrated (Figure C).
      Biological Information
      ImmunogenKLH-conjugated, synthetic peptide containing the sequence …HR[mmK]V…, in which mmK corresponds to monomethyl-lysine at residue 20 of human histone H4.
      SpecificityRecognizes monomethyl-histone H4 (Lys20), Mr ~10kDa.
      Species Reactivity
      • Human
      Species Reactivity NoteHuman. The immunizing sequence is conserved from Tetrahymena to human, so broad species cross-reactivity is expected.

      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 is intronless and encodes a member of the histone H4 family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in the large histone gene cluster on chromosome 6.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P62805 # 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: 103 amino acids; 11367 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.
      PTM: Symmetric dimethylation on Arg-4 by the PRDM1/PRMT5 complex may play a crucial role in the germ-cell lineage (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.
      SIMILARITY: SwissProt: P62805 ## Belongs to the histone H4 family.
