Tel1ATM and Rad3ATR kinases promote Ccq1-Est1 interaction to maintain telomeres in fission yeast
2011
In fission yeast, the DNA damage kinases Tel1 (ATM) and Rad3 (ATR) are required to recruit telomerase to telomere. The relevant target for these kinases is now identified: shelterin subunit Ccq1 is phosphorylated at Thr93 in a Tel1/Rad3-dependent manner, and this modification is essential for Ccq1 to interact with telomerase subunit Est1.
