关于 H1-7

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。核小体由大约 146 bp 的 DNA 组成，包裹在由四种核心组蛋白 (H2A、H2B、H3 和 H4) 中的每一种成对组成的组蛋白八聚体周围。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，编码一种复制独立组蛋白，该组蛋白是组蛋白 H1 家族的一员。相关的小鼠基因编码精子发生和男性生育能力所需的睾丸特异性蛋白质。[RefSeq 提供，2015 年 10 月]

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. This gene is intronless and encodes a replication-independent histone that is a member of the histone H1 family. The related mouse gene encodes a testis specific protein that is required for spermatogenesis and male fertility. [provided by RefSeq, Oct 2015]
