摘要

在染色质复制过程中,有效克服核小体屏障和准确维持相关组蛋白标记对于细胞的正常功能至关重要。最近的研究揭示了新的蛋白因子和组蛋白修饰有助于克服核小体屏障,并表明DNA环在原始组蛋白复制过程中的存活中起重要作用。这些研究提出了将组蛋白密码传递给下一代细胞的新的可能机制。

Chromatin replication: TRANSmitting the histone code.

Efficient overcoming of the nucleosomal barrier and accurate maintenance of associated histone marks during chromatin replication are essential for normal functioning of the cell. Recent studies revealed new protein factors and histone modifications contributing to overcoming the nucleosomal barrier, and suggested an important role for DNA looping in survival of the original histones during replication. These studies suggest new possible mechanisms for transmitting the histone code to next generations of cells.
