title: Telomere biology: a new player in the end zone.
abstract: Yet another protein has been added to the crowd of players found at the ends of chromosomes. Known variously as PTOP, PIP1 or TINT1, this negative regulator of telomere length connects some of the key proteins already known to be present - TRF1, TIN2, POT1, and TRF2 - and adds even more complexity to telomere protein interactions.
