General description
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.
Immunogen
KLH conjugated synthetic peptide (ARTMe2KQTAR-GC) corresponding to amino acids 1-8 of human Histone H3.
Epitope: dimethylated Histone H3 (Lys4)
