H2BC5基因编码功能及结构描述
组蛋白是构成真核生物染色体纤维核小体结构的基本核蛋白核小体由大约146 bp的DNA包裹在组蛋白八聚体周围，该组蛋白八聚体由四个核心组蛋白（H2A、H2B、H3和H4）中的每一个组成。染色质纤维通过连接组蛋白h1与核小体之间的dna相互作用进一步紧密，形成高阶染色质结构。这个基因是无内含子的，编码一个复制依赖性组蛋白，它是组蛋白H2B家族的成员在6p22-p21.3号染色体上的大组蛋白基因簇中发现了两个编码相同蛋白质的转录本。[由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. 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-dependent histone that is a member of the histone H2B family. Two transcripts that encode the same protein have been identified for this gene, which is found in the large histone gene cluster on chromosome 6p22-p21.3. [provided by RefSeq, Aug 2015]
