53BP1* binds to DNA and stops DNA resection and therefore stops HR during cell cycle exept S-pthase, because 53BP1*
is phosphorylated by CDK1(CDC2) during S-phase, this phosphorylation inhibits 53BP1* activity

53BP1* binds to DNA and stops DNA resection and therefore stops HR during cell cycle except S-phase, because 53BP1* is phosphorylated by CDK1(CDC2) during S-phase, this phosphorylation inhibits 53BP1* activity.
