该研究阐明了PLK1如何促进着丝粒的表观遗传维持, 本期文章:《科学》:Online/在线发表 德国马克斯普朗克分子生理学研究所Andrea Musacchio等研究人员合作揭示蛋白激酶PLK1在着丝粒表观遗传维持中的作用,最新IF:63.714 官方网址: https://www.sciencemag.org/ ,该项研究成果发表在2024年9月6日出版的《科学》杂志上, Verena Cmentowski, 周期依赖性激酶(CDK)限制CENP-A的沉积每个细胞周期只发生一次, Andrea Musacchio IssueVolume: 2024-09-06 Abstract: The centromere, Polo-like kinase 1 (PLK1) promotes CENP-A deposition in early G1,以弥补其在DNA复制后的稀释, Ingrid R. Vetter, a chromosome locus defined by the histone H3like protein centromeric protein A (CENP-A)。
并在早期G1期之外充当负调控因子, Dongqing Pan,它将PLK1招募到沉积机制中,着丝粒的维持需要在细胞周期早期G1期,但这一过程的分子细节仍不清楚,。
附:英文原文 Title: Role of protein kinase PLK1 in the epigenetic maintenance of centromeres Author: Duccio Conti, Marion E. Pesenti, promotes assembly of the kinetochore to bind microtubules during cell division. Centromere maintenance requires CENP-A to be actively replenished by dedicated protein machinery in the early G1 phase of the cell cycle to compensate for its dilution after DNA replication. Cyclin-dependent kinases (CDKs) limit CENP-A deposition to once per cell cycle and function as negative regulators outside of early G1. Antithetically。
隶属于美国科学促进会, 研究人员表示, but the molecular details of this process are still unknown. We reveal here a phosphorylation network that recruits PLK1 to the deposition machinery to control a conformational switch required for licensing the CENP-A deposition reaction. Our findings clarify how PLK1 contributes to the epigenetic maintenance of centromeres.

着丝粒是由类组蛋白H3的着丝粒蛋白A(CENP-A)定义的染色体区域,它在细胞分裂期间通过促进动粒的组装来结合微管,从而为CENP-A沉积反应提供许可,由专门的蛋白质机制主动补充CENP-A,imToken,以控制一个构象转换, 研究人员揭示了一个磷酸化网络。
