The TRF1 subunit of the shelterin complex controls telomere length by regulating telomerase access to chromosome ends. Work from Zeng et al. (2010) now reveals in atomic detail how a battle between the SCF(FBX4) ubiquitin ligase and the shelterin component TIN2 controls TRF1 abundance and telomere length homeostasis.
庇护体复合物的 TRF1 亚基通过调节端粒酶进入染色体末端来控制端粒长度。曾等人(2010 年)的工作现在以原子细节揭示了 SCF(FBX4)泛素连接酶和庇护体成分 TIN2 之间的一场战斗如何控制 TRF1 丰度和端粒长度的动态平衡。
