Histone chaperones also participate in the selective deposition of histone variants, which are functionally distinct from canonical histones. For example, HIRA is a chaperone that specifically deposits the …

在生物学中，组蛋白（histone）是一类富含赖氨酸和精氨酸残基的高度碱性蛋白质，这些蛋白质主要存在于真核细胞的细胞核中，以及在大多数古菌域中也有发现。 组蛋白作为DNA的“卷轴”，DNA会围绕 …

组蛋白 （histone）是真核生物体细胞染色质中的一种碱性蛋白质，和DNA共同组成 核小体结构。 它们是染色质的主要蛋白质组分，作为DNA缠绕的线轴，在基因调控中发挥重要作用。

A histone is a type of protein that plays a critical role in the structural organization and regulation of DNA within the nucleus of eukaryotic cells.

3 days ago · Histone. Eight histone proteins can come together to make up something called a nucleosome. A nucleosome is like a tiny spool that DNA can wind around. So histones play an …

A protein that is part of the histone family of basic proteins which associate with DNA in the nucleus and help to condense the DNA into a smaller volume.

Histone modifications have been implicated in maintaining the transcriptionally poised state of important genesin embryonic stem cells. Histone modifications are believed to be responsible for …

组织蛋白H2A，H2B，H3和H4被称为核心组织蛋白（Core Histone），而组织蛋白H1/H5被称为连接组织蛋白（Linker Histone）。 在H2A、H2B、H3及H4這四種組織蛋白中的其中兩種稱為「核心組織蛋 …

Histone proteins are highly conserved among all eukaryotes. They have two important functions in the cell: to package the genomic DNA and to regulate gene accessibility.

Aug 22, 2025 · When DNA is damaged, histone modifications can help make affected DNA regions more accessible to repair enzymes. For example, specific histone modifications can recruit repair …
