The CST Complex and Telomere Maintenance: The Exception Becomes the Rule

Telomeres are bound and stabilized by two complexes-CST and shelterin-thought to be species specific and virtually unrelated. In this issue of Molecular Cell, Miyake et al. (2009) and Surovtseva et al. (2009) provide evidence that these complexes coexist and function at telomeres in many species.
