染色质在真核生物基因组调控中起着重要作用,并且越来越多的人认识到表观遗传过程在人类健康和疾病中的重要性,强调需要了解核小体的结构和功能。染色质结构研究的最新进展,包括包含Widom 601序列的核小体的第一结构和染色质蛋白-核小体组装的结构,为核小体DNA的拉伸、核小体定位、金属离子、药物和治疗候选物与核小体的结合以及核蛋白对核小体的识别提供了新的见解。这些发现确保了解开染色质结构属性的前景光明。
Chromatin plays a fundamental role in eukaryotic genomic regulation, and the increasing awareness of the importance of epigenetic processes in human health and disease emphasizes the need for understanding the structure and function of the nucleosome. Recent advances in chromatin structural studies, including the first structures of nucleosomes containing the Widom 601 sequence and the structure of a chromatin protein-nucleosome assembly, have provided new insight into stretching of nucleosomal DNA, nucleosome positioning, binding of metal ions, drugs and therapeutic candidates to nucleosomes, and nucleosome recognition by nuclear proteins. These discoveries ensure promising future prospects for unravelling structural attributes of chromatin.
