<正>Mammalian shelterin proteins POT1 and TPP1 form a stable heterodimer that protects chromosome ends and regulates telomerase-mediated telomere extension.However,how POT1 interacts with TPP1 to form a heterodimer remains unknown.Here we present the crystal structure of the C-terminal portion of human POT1(POT1C)complexed with the POT1-binding-
