βarr1 post transcriptionally regulates expression levels of 53BP1. a Cell lysates derived from WT, βarr1−/−, βarr2−/− MEFs, and βarr1−/−; βarr2−/− double knockout MEFs (DKO) were immunoblotted and analyzed using the indicated antibodies. b Real-time PCR analysis of 53BP1 mRNA levels in paired WT and βarr1−/− MEFs following exposure to IR
