Descripción general
Histones are octameric proteins containing H3, H4, H2A and H2B. It is the core protein around which DNA is wound forming the nucleosome structure. The core histone proteins contain globular domains. Each protein is composed of basic amino acids at its N-terminal. The H2A has an extra amino acid at its C-terminal end forming a histone tail. The nucleosome structure is stabilized by the linker histones during chromatin condensation.[1]
Aplicación
Histone from calf thymus has been used:
- in methyltransferase reaction mixture for methyltransferase assay[2]
- in in vitro binding assay, to explore the potential binding of the MORF4 (mortality factor on chromosome 4) - related gene on chromosome 15 (MRG15) chromo domain with histone[3]
- in in vitro coculture assays, to stimulate liver resident Kupffer cells[4]
Acciones bioquímicas o fisiológicas
The core histones are involved in histone-histone interactions and maintains the organization of the nucleosomal DNA. The histone tail helps in forming higher-order nucleosomal structures. The overall structure and action of chromatin fiber is regulated by histone modifications.[1]

Histones are highly covalently modified, but the functions of many of these modifications remain unknown. In particular, it is unclear how histone marks are coupled to cellular metabolism and how this coupling affects chromatin architecture. We identified histone H3 Lys14
