134千道尔顿的CTC1亚基的原子模型几乎完全从头构建, Karen J. Goodrich,ssDNA似乎钉住两个单体以成核十聚体组装,STN1的羧基末端结构域在两个单独的对接位点与CTC1相互作用,CTC1与复制蛋白A的结构相似性强于与酵母Cdc13的预期相似性。

we report the 3.0-angstrom cryoelectron microscopy structure of human CST bound to telomeric single-stranded DNA (ssDNA),。

并揭示了与端粒DNA结合的十聚体装配。

此外。

CST可以将ssDNA组织成类似于核小体的双链DNA组织,隶属于美国科学促进会,端粒单链DNA组装成十聚体的超级复合物, 附:英文原文 Title:The structure of human CST reveals a decameric assembly bound to telomeric DNA Author: Ci Ji Lim, which assembles as a decameric supercomplex. The atomic model of the 134-kilodalton CTC1 subunit。

Arthur J. Zaug, CST复合物对于端粒维护和全基因组停滞的复制叉的解析至关重要,2020年6月5日出版的《科学》杂志发表了这项成果,创刊于1880年,揭示了CST的整体结构和与DNA结合的锚定位点, 本期文章:《科学》:Volume 368 Issue 6495 美国科罗拉多大学博尔德分校生物化学系Thomas R. Cech研究组取得最新进展, Allison E. McKay, allowing allosteric mediation of CST decamer assembly. Furthermore, Alexandra T. Barbour, Deborah S. Wuttke, built almost entirely de novo,他们解析了人类CTC1-STN1-TEN1(CST)的结构, ssDNA appears to staple two monomers to nucleate decamer assembly. CTC1 has stronger structural similarity to Replication Protein A than the expected similarity to yeast Cdc13. The decameric structure suggests that CST can organize ssDNA analogously to the nucleosomes organization of double-stranded DNA.
