关于 H3C7

功能概要

组蛋白是基本的核蛋白，负责真核生物染色体纤维的核小体结构。这种结构由大约 146 bp 的 DNA 组成，核小体是一个八聚体，由四种核心组蛋白 (H2A、H2B、H3 和 H4) 中的每一种成对组成。染色质纤维通过接头组蛋白 H1 与核小体之间的 DNA 相互作用进一步压缩，形成更高阶的染色质结构。该基因是无内含子的，编码复制依赖组蛋白，该组蛋白是组蛋白 H3 家族的成员。该基因的转录本缺少 polyA 尾巴；相反，它们包含回文终止元素。该基因存在于染色体 6p22-p21.3 上的大组蛋白基因簇中。[RefSeq 提供，2015 年 8 月]

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. This structure consists of approximately 146 bp of DNA wrapped around a nucleosome, an 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. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is found in the large histone gene cluster on chromosome 6p22-p21.3.
