Description générale

Human recombinant histone octamer consisting of 2 molecules each of histones H2A (GenBank Accession No. NM_033445) amino acids 2-130(end) with a N-terminal His-tag, H2B (GenBank Accession No. NM_003528) amino acids 2-126(end) with a N-terminal His-tag, H3 (GenBank Accession No. NM_003532) amino acids 2-137(end) with a N-terminal His-tag, and H4 (GenBank Accession No. NM_003548) amino acids 2-103(end) with a N-terminal His-tag, expressed in an E. coli expression system.

Actions biochimiques/physiologiques

The nuclear DNA in eukaryotes is found to be associated with histones to form a compact complex called nucleosome. Histones neutralize the electrostatic nature of DNA and function as scaffolding proteins. Each core nucleosome contains two copies each of the core histones H2A, H2B, H3, and H4 to form an octameric complex. This octameric complex contains a central (H3-H4)2 tetramer flanked on both sides with H2A-H2B dimers. The octamer complex function in various stages of chromosome function, chromatin assembly and nucleosome formation. The histone dimer-tetramer interactions are also important in RNA transcription.

In eukaryotes, chromatin remodelling complexes are shown to be responsible for nucleosome mobility, leading to increased accessibility of DNA for DNA binding proteins. Although the existence of such complexes in plants has been surmised mainly at the genetic level from
