A CPC-shelterin-BTR axis regulates mitotic telomere deprotection
Abstract Telomeres prevent ATM activation by sequestering chromosome termini within telomere loops (t-loops).Mitotic arrest promotes telomere linearity and a localized ATM-dependent telomere DNA damage response (DDR) through an unknown mechanism.Using unbiased interactomics, biochemical screening, molecular biology, and super-resolution imaging, we
