摘要：

DNA-activated protein kinase (DNA-PK) is a nuclear serine/threonine protein kinase that is activated in vitro by DNA fragments. The cellular targets of DNA-PK are nuclear, DNA-binding, regulatory proteins including Sp1, Fos, Jun, Myc, the tumor suppressor protein p53, and RNA polymerase II. These characteristics suggest a role for DNA-PK in coordinating nuclear processes and as a modulator of checkpoint mechanisms activated by DNA damage.
