Merck, 14-155, Histone H1 Protein, 20 mg

General description
H1 and related linker histones are important both for maintenance of higher-order chromatin structure and for the regulation of gene expression. Nucleosomal stabilization is provided through the binding of histone H1 to the nucleosomal dyad and the linker DNA entering and exiting the core particle. Additional experimental evidence illustrates the influence of histone H1 on chromatin arrangement and compaction. The family of histone H1 proteins contains five somatic variants (H1.1, H1.2, H1.3, H1.4 and H1.5) which are expressed in nearly all cell types.
