Human Histone H1, also known as H1F0, (GenBank Accession No. NM_005318), a.a. 2-194(end) with N-terminal His-tag, MW = 21.7 kDa, expressed in an E. coli expression system.
Background
Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fiber. Histones H1 are necessary for the condensation of nucleosome chains into higher-order structured fibers. Acts as a regulator of individual gene transcription through chromatin remodeling, nucleosome spacing and DNA methylation.
Immunogen Region
2-194(end)
Tag
N-terminal His-tag
Formulation
8 mM phosphate pH 7.4, 110 mM NaCl, 2.2 mM KCl, 3 mM DTT, and 20% glycerol.
Species
Human
Application
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.
