Histone tails and their function in chromatin formation. Histone H2B is a lightweight structural protein made of 126 amino acids. [2] Many of these amino acids have a positive charge at cellular pH, which allows them to interact with the negatively charged phosphate groups in DNA. [3]
The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H2B family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element.
Three histone modifications are particularly associated with repressed genes: Trimethylation of H3 lysine 27 (H3K27me3) This histone modification is deposited by the polycomb complex PRC2. [62] It is a clear marker of gene repression, [63] and is likely bound by other proteins to exert a repressive function.
The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H2B family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element.
Histone H2B type 1-C/E/F/G/I is a protein that in humans is encoded by the HIST1H2BG gene. [ 5 ] [ 6 ] [ 7 ] Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes.
The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a member of the histone H2B family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif.
