The DNA-dependent protein kinase.
The DNA-dependent protein kinase (DNA–PK) is a nuclear serine/threonine protein kinase that is activated upon association with DNA. Biochemical and genetic data have revealed DNA–PK to be composed of a large catalytic subunit, termed DNA–PKcs, and a regulatory factor termed Ku. In recent years, mammalian DNA–PK has been shown to be a crucial component of both the DNA double-strand break (DSB) r...

متن کاملDNA looping by Ku and the DNA-dependent protein kinase.
The DNA-dependent protein kinase (DNA-PK) is required for DNA double-strand break (DSB) repair and immunoglobulin gene rearrangement and may play a role in the regulation of transcription. The DNA-PK holoenzyme is composed of three polypeptide subunits: the DNA binding Ku70/86 heterodimer and an approximately 460-kDa catalytic subunit (DNA-PKcs). DNA-PK has been hypothesized to assemble at DNA ...

We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...
متن کاملProtein phosphatases regulate DNA-dependent protein kinase activity.
DNA-dependent protein kinase (DNA-PK) is a complex of DNA-PK catalytic subunit (DNA-PKcs) and the DNA end-binding Ku70/Ku80 heterodimer. DNA-PK is required for DNA double strand break repair by the process of nonhomologous end joining. Nonhomologous end joining is a major mechanism for the repair of DNA double strand breaks in mammalian cells. As such, DNA-PK plays essential roles in the cellul...
