Overview
Ku70 a mini-chromosome maintenance protein, essential for the initiation of eukaryotic genome replication. Allows DNA to undergo a single round of replication per cell cycle. Required for the entry in S phase and for cell division. Note: This description may include information from UniProtKB.
Protein type: EC 4.2.99.-; DNA binding protein; Helicase; DNA repair; EC 3.6.4.-
Cellular Component: nucleoplasm; transcription factor complex; nuclear telomere cap complex; membrane; cytoplasm; DNA-dependent protein kinase complex; nucleus
Molecular Function: protein C-terminus binding; ATP-dependent DNA helicase activity; identical protein binding; protein binding; DNA binding; double-stranded DNA binding; double-stranded telomeric DNA binding; 5'-deoxyribose-5-phosphate lyase activity; ATP binding
Biological Process: positive regulation of neurogenesis; V(D)J recombination; viral reproduction; transcription, DNA-dependent; positive regulation of transcription, DNA-dependent; DNA repair; double-strand break repair via nonhomologous end joining; DNA ligation; double-strand break repair; positive regulation of transcription from RNA polymerase II promoter; response to ionizing radiation; negative regulation of transcription, DNA-dependent; telomere maintenance
Reference #:  P12956 (UniProtKB)
