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. Phosphorylation at Ser10, Ser28 and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis. In mammals, phosphorylation of Thr11 modification is restricted to the centromeric region while in plant cells, phosphorylation of Thr11 was distributed along the entire length of condensed chromosomes. Mitosis-specific phosphorylation of histone H3 at Thr11 is mediated by Dlk/ZIP kinase.

ApplicationAnti-phospho-Histone H3 (Thr11) Antibody, clone MC83 is a rabbit monoclonal antibody for detection of phospho-Histone H3 (Thr11) also known as H3T11P, Histone H3 (phospho T11) & has been validated in WB, PIA, Mplex.
Key Applications
  • Western Blotting
  • Peptide Inhibition Assay
  • Multiplexing
Application NotesImmunoblot Analysis:
A 1:500-1:2000 dilution of this lot detected phosphorylated histone H3 in acid extracted proteins from mitotic HeLa cells treated with colcemid, but not unmodified recombinant histone H3 (Catalog # 14-494).

Western Blot Analysis:
A 1:5,000 dilution of a previous lot detected phosphorylated histone H3 in acid extracted proteins from mitotic HeLa cells treated with colcemid, but not unmodified recombinant histone H3 (Catalog # 14-494).


Multiplexing:
Beadlyte® Histone-Peptide Specificity Assay: 1:1,000-1:50,000 dilutions of a previous lot were incubated with histone H3 peptides containing various modifications conjugated to Luminex® microspheres. Only the peptide containing phospho-threonine 11 was
detected (Figure C).

Peptide Inhibition Analysis: 1 μM of histone H3 peptide containing phospho-threonine 11 abolished detection of histone H3 by anti-phospho-Histone H3 (Thr11), clone MC83 in immunoblot analysis of acid extracts from
colcemid treated HeLa cells (Figure D, lane 4).

Entrez Gene Number
Entrez Gene SummaryHistones 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. This gene is intronless and encodes a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3.

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.
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.
