Recombinant Human HIST3H3 protein, His-tagged
Recombinant Human HIST3H3(2–136 aa) fused with N-terminal Met-Ala-Cys-6xHis-tag was expressed in E. coli.
Histones 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 replication-dependent histone that is 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.
8 mM PBS pH 7.4, 110 mM NaCl, 2.2 mM KCl, 20% glycerol and 3 mM DTT.
Useful as a substrate for histone methyltransferase and acetyltransferase assays. Ideal for screening small molecular inhibitors of histone modifying enzymes for drug discovery and HTS applications.
> 6 months at -80 centigrade. Avoid freeze/thaw cycles.
