title: Mitochondria and telomeres: the promiscuous roles of TIN2.
abstract: Telomeric proteins are best known for their role in maintenance of telomere function. In this issue, Chen et al. (2012) demonstrate that the telomeric protein TIN2 can specifically localize to the mitochondria, where it can regulate metabolism and ROS production.
