摘要

33染色质由核小体组成,每个核小体由组蛋白H3、H4、H2A和H2B各两个拷贝的八聚体组成。染色质对转录、复制、DNA修复和基因组稳定性的其他方面的控制至关重要。在人类中,有不同的组蛋白H3变体。H3.3蛋白在整个细胞周期和静止细胞[1]中表达,而H3.1和H3.2仅在s期[1]中表达。

The Clinicopathological and Genetic Characteristics of High-grade Gliomas with Histone H3.3 G34 Mutation in Teenagers and Young adults
33 Chromatin is composed of nucleosomes, with each nucleosome consisting of an octamer of two copies each of histones H3, H4, H2A, and H2B. Chromatin is critical for the control of transcription, replication, DNA repair and other aspects of genomic stability. In humans, there are different histone H3 variants. H3.3 proteins are expressed thoughout the cell cycle as well as in quiescent cells [1], while H3.1 and H3.2 are expressed only during the S-phase [2].
