Telomere protection by TPP1/POT1 requires tethering to TIN2
To prevent ATR activation, telomeres deploy the single-stranded DNA binding activity of TPP1/POT1a. POT1a blocks the binding of RPA to telomeres, suggesting that ATR is repressed through RPA exclusion. However, comparison on the DNA binding affinities and abundance of TPP1/POT1a and RPA indicates th...
