At the end, it is POT1 again: Phosphorylation allows human telomeric protein POT1 to recruit the C-rich strand end replication machinery

Recently in Cell, Cai et al.(1) reported how phosphorylation of human shelterin protein POT1 allows it to recruit the telomeric C-rich strand replication machinery, providing mechanistic insights into an understudied area of telomere biology with implications for telomere biology disorders.
