Gene Information

human ... HIST1H3E(8353)

General description

The mammalian chromatin is present in nucleosomes, made of histone octamers (H2A,H2B,H3,H4)2. Mammals contain three main classes of histone H3 variants: the replicative histones (H3.1 and H3.2), the replacement histone (H3.3) and the centromeric histone (Cenp-A).
Human Histone 3 (GenBank Accession No. NM_003532), (amino acid 2-58) with N-terminal GST tag, MW = 32kDa, expressed in an Escherichia coli expression system.

Application

Suitable substrate for histone methyltransferases

Biochem/physiol Actions

Histone proteins are basic building blocks of chromatin. H3.1 (also referred to as HIST1H3E) is mainly expressed in the S phase and is termed as replication-dependent histone. Selective methylation of H3.1 controls replication in heterochromatin area.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 20% glycerol and 3 mM DTT.

Preparation Note

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

The mechanism by which newly synthesized histones are imported into the nucleus and deposited onto replicating chromatin alongside segregating nucleosomal counterparts is poorly understood, yet this program is expected to bear on the putative epigenetic nature of histone post-translational modifications.

Histone posttranslational modifications (PTMs) and sequence variants regulate genome function. Although accumulating evidence links particular PTM patterns with specific genomic loci, our knowledge concerning where and when these PTMs are imposed remains limited. Here, we find that lysine methylation is
