Supplementary information

Ku70 also known as XRCC6 or K331 is a DNA repair protein with a molecular mass of approximately 70 kDa. It belongs to the Ku protein family which includes Ku80. This protein expresses mainly in the nucleus of cells across various tissue types. As a part of a heterodimer together with Ku80 Ku70 forms the Ku70/Ku80 complex which binds to free DNA ends allowing DNA repair processes to occur efficiently.

Biological function summary

The Ku70 protein plays a significant role in maintaining genomic stability. It is an important component of the non-homologous end joining (NHEJ) pathway a primary mechanism for repairing double-strand breaks in DNA. By forming the Ku70/Ku80 complex it accurately aligns DNA ends to facilitate repair and prevent chromosomal abnormalities. The Ku70 protein also involves in telomere maintenance and can influence cell cycle regulation.

Pathways

Ku70 contributes mainly to the NHEJ DNA repair pathway. This pathway is important for cellular response to DNA damage and involves other proteins such as DNA-PKcs (DNA-dependent protein kinase catalytic subunit) and XRCC4. Ku70's interaction with DNA-PKcs enables the activation of its kinase activity which is essential for the repair process. Additionally Ku70 is involved in the homologous recombination pathway where it interacts with proteins like Rad51 to ensure repair fidelity.

Research links the Ku70 protein to cancer and neurodegenerative diseases. Dysregulation or mutations affecting Ku70 can lead to genomic instability contributing to cancer development. Ku70 also shows connections to neurodegenerative conditions like Alzheimer's disease where its role in DNA repair and apoptosis regulation may impact neuronal cell survival. Interactions with p53 a protein important for DNA damage response further underline Ku70's influence in these disease contexts.

Target data

Single-stranded DNA-dependent ATP-dependent helicase that plays a key role in DNA non-homologous end joining (NHEJ) by recruiting DNA-PK to DNA (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). Required for double-strand break repair and V(D)J recombination (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). Also has a role in chromosome translocation (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). Has a role in chromosome translocation (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). The DNA helicase II complex binds preferentially to fork-like ends of double-stranded DNA in a cell cycle-dependent manner (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). It works in the 3'-5' direction (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). During NHEJ, the XRCC5-XRRC6 dimer performs the recognition step : it recognizes and binds to the broken ends of the DNA and protects them from further resection (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). Binding to DNA may be mediated by XRCC6 (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). The XRCC5-XRRC6 dimer acts as a regulatory subunit of the DNA-dependent protein kinase complex DNA-PK by increasing the affinity of the catalytic subunit PRKDC to DNA by 100-fold (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). The XRCC5-XRRC6 dimer is probably involved in stabilizing broken DNA ends and bringing them together (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). The assembly of the DNA-PK complex to DNA ends is required for the NHEJ ligation step (PubMed : 11493912, PubMed : 12145306, PubMed : 20493174, PubMed : 2466842, PubMed : 7957065, PubMed : 8621488, PubMed : 9742108). Probably also acts as a 5'-deoxyribose-5-phosphate lyase (5'-dRP lyase), by catalyzing the beta-elimination of the 5' deoxyribose-5-phosphate at an abasic site near double-strand breaks (PubMed : 20383123). 5'-dRP lyase activity allows to 'clean' the termini of abasic sites, a class of nucleotide damage commonly associated with strand breaks, before such broken ends can be joined (PubMed : 20383123). The XRCC5-XRRC6 dimer together with APEX1 acts as a negative regulator of transcription (PubMed : 8621488). In association with NAA15, the XRCC5-XRRC6 dimer binds to the osteocalcin promoter and activates osteocalcin expression (PubMed : 12145306). Plays a role in the regulation of DNA virus-mediated innate immune response by assembling into the HDP-RNP complex, a complex that serves as a platform for IRF3 phosphorylation and subsequent innate immune response activation through the cGAS-STING pathway (PubMed : 28712728).
