WebFor ATR, the DNA damage sensor is ATRIP [175]. ATM can functionally interact with DNA-PK cs and ATR. ATM and DNA-PK cs collaborate in response to DSB [176–178]. Moreover, the MRN complex cooperates with ATM to resect a DNA end for the generation of a 3′-single strand tail, which recruits replication protein A to set the stage for ATR ... WebApr 21, 2024 · ATM and ATR kinases are two master regulators of DNA damage responses. ATR, a serine/threonine-protein kinase belonging to the phosphatidylinositol 3-kinase-related kinase (PIKK) family of proteins, is a key regulator of the DNA replication stress response (RSR) and DNA-damage activated checkpoints [ 70 ].
