Protein kinase, DNA-activated, catalytic polypeptide

DNA-PKcs, DNA-dependent protein kinase catalytic subunit, P350, DNA-PK catalytic subunit
This gene encodes the catalytic subunit of the DNA-dependent protein kinase (DNA-PK). It functions with the Ku70/Ku80 heterodimer protein in DNA double strand break repair and recombination. The protein encoded is a member of the PI3/PI4-kinase family.[provided by RefSeq, Jul 2010] (from NCBI)
