Histone H3 (1-20) K4Me3, pS10-GG-[Lys(5-FAM)] ART-[K(Me3)]-QTARK-[pS]-TGGKAPRKQL-GG-[K(5-FAM)]-amide


Histone 3 (H3) is one of the four core histones fundamental for compacting eukaryotic DNA into the nucleosome. Lysine 4 of this peptide has been tri-methylated, serine 10 has been phosphorylated and the C-terminal has been labelled with 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag.

Histone 3 (H3) is one of the four core histones (H2A, H2B, H3 and H4) fundamental in compacting eukaryotic DNA into the nucleosome. The nucleosome arises when 147 base pairs of DNA wrap around a H3-H4 tetramer and two H2A-H2B dimers, forming the histone octamer core. Similar to the other core histone, H3 has a globular domain and a flexible N-terminal domain, “histone tail” which can undergo modifications such as acetylation, methylation, phosphorylation and ubiquitination. The transcriptional activation or silencing of the chromatin is controlled by ATP-dependent chromatin remodelling factors and histone modifying enzymes which target histone proteins. Both processes function to alter the positioning of the nucleosome, allowing the DNA it to be either available or inaccessible to the transcription machinery.

The lysine at position 4 of this peptide has been tri-methylated and it is implicated in studies that this modification may remodel the chromatin so that it is more accessible to transcription factors, which may ultimately increase the level of gene expression. Moreover, the serine at position 10 has been phosphorylated, and studies have suggested that this may induce chromatin condensation, and subsequently repress transcription and gene expression.

Histone H3 (1-20) K4Me3, pS10-GG-[Lys(5-FAM)] has a C-terminal GKK linker labelled with 5-Carboxyfluorescein (5-FAM), a widely used green fluorescent tag.
