着丝粒在细胞分裂时指导忠实的染色体遗传,但不是由保守的 DNA 序列定义的。相反,含有组蛋白 H3 变体的染色质的特殊形式 CENP-A,在表观遗传学上指定着丝粒位置。我们讨论了当前的模型,其中 CENP-A 除了在有丝分裂中生成着丝粒的基础染色质之外,还充当整个细胞周期中着丝粒的标记。最近的实验表明,含有 CENP-A 的核小体的工程阵列足以充当着丝粒形成的位点,并用于播种在细胞世代中自我繁殖的着丝粒染色质。最后,最近对含有 CENP-A 的组蛋白复合物在组装成核小体之前和之后的结构和动态研究提供了模型来解释着丝粒的潜在分子机制。
Centromeres direct faithful chromosome inheritance at cell division but are not defined by a conserved DNA sequence. Instead, a specialized form of chromatin containing the histone H3 variant, CENP-A, epigenetically specifies centromere location. We discuss current models where CENP-A serves as the marker for the centromere during the entire cell cycle in addition to generating the foundational chromatin for the kinetochore in mitosis. Recent elegant experiments indicate that engineered arrays of CENP-A-containing nucleosomes are sufficient to serve as the site of kinetochore formation and for seeding centromeric chromatin that self-propagates through cell generations. Finally, recent structural and dynamic studies of CENP-A-containing histone complexes—before and after assembly into nucleosomes—provide models to explain underlying molecular mechanisms at the centromere.
