背景介绍
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. HIST3H2BB is a replication-dependent histone that is a member of the histone H2B family.

文献和实验Histone Acetylation and Deacetylation
transcription (1 ,2 ). DNA is packaged into chromatin, a highly organized and dynamic protein-DNA complex. The fundamental subunit of chromatin, the nucleosome, is composed of an octomer of four core histones, an H3/H4 tetramer and two H2A/H2B dimers, surrounded
组蛋白是和染色体相联的最主要的蛋白质。它的作用是和染色体中的 DNA 的负电荷结合。组蛋白是比较小的碱性蛋白;在细胞正常 pH 值时,组蛋白带有正电荷,这样它们就可以和 DNA 结合,这个正电荷主要存在于碱性氨基酸 Lys 和 Arg 的 -NH3 上。其实,组蛋白约含 25% 的 Arg 和 Lys 。比其他蛋白的 Arg , Lys 的含量都多。和真核 DNA 结合的有 5 种类型的组蛋白: H1 , H2A , H2B , H3
组蛋白是真核生物染色体的基本结构蛋白, 是一类小分子碱性蛋白质, 有五种类型:H1 、H2A 、H2B 、H3 、H4,它们富含带正电荷的碱性氨基酸, 能够同DNA中带负电荷的磷酸基团相互作用。 组蛋白的基因非常保守。亲缘关系较远的种属中, 四种组蛋白(H2A、H2A、H3、H4)氨基酸序列都非常相似, 如海胆组织H3的氨基酸序列与来自小牛胸腺的H3的氨基酸序列间只有一个氨基酸的差异, 小牛胸腺的H3的氨基酸序列与豌豆的H3也只有4个氨基酸不同。不同生物的H1序列变化
