Supplementary information

The Ku80 protein also known as Ku p70 Ku antigen p70 and by gene identifiers such as Ku80 hum39 and 5c5 functions critically in DNA repair processes. With a molecular mass of approximately 80 kDa Ku80 is ubiquitously expressed in mammalian cells. It is an important component of the Ku heterodimer working with its partner Ku70 to detect and bind DNA double-strand breaks (DSBs). This action initiates repair by aligning with DNA ends to prevent break processing and sustain genome integrity.
Biological function summary

The Ku80 protein executes an important role in maintaining cellular stability by participating in the non-homologous end joining (NHEJ) pathway. Ku80 forms a complex with DNA-PKcs (DNA-dependent protein kinase catalytic subunit) which activates the kinase to phosphorylate itself and other proteins facilitating the repair of DSBs. Its expression is significant in tissues that undergo high rates of cellular turnover and are experienced with DNA damage where the DNA repair mechanisms are important for regular cell cycle progression.

Pathways

DNA repair and V(D)J recombination are principal domains where Ku80 shows its influence. In the context of DNA repair Ku80's partnership with DNA-PKcs as part of the NHEJ repair pathway is fundamental in fixing DNA damage from environmental insults or normal cellular metabolism. In the immune development process through V(D)J recombination Ku80 partners with other proteins like the Artemis complex to perform programmed DNA rearrangements required for the diversity of immune receptors.

Ku80 has a significant relation to cancer and immune deficiencies. Defects in Ku80 function can lead to increased sensitivity to ionizing radiation and a higher propensity for cancer development because of impaired DNA repair capabilities. Moreover in immune-related disorders inadequate Ku80 performance affects the maturation of lymphocytes leading to immune system malfunction. Its malfunctioning connection with proteins like DNA-PKcs and Artemis highlights its critical roles in both tumor suppression and immune system competence.

Target data

DNA-binding protein critical for the DNA damage response, specifically in repairing double-strand breaks (DSBs) via the classical non-homologous end joining (NHEJ) pathway. It forms a heterodimer with XRCC6 (Ku70), creating the Ku70 : Ku80 heterodimer (Ku complex), which serves as a DNA end-binding complex. It primarily binds DSBs and recruits essential repair factors, assembling the core long-range NHEJ complex to facilitate the alignment and ligation of broken DNA ends (PubMed : 11493912, PubMed : 33854234, PubMed : 34352203). This pathway ensures the rapid repair of cytotoxic and mutagenic DSBs and contributes to the generation of diversity in T-cell receptors and antibodies through mechanisms such as V(D)J recombination (PubMed : 9742108). Likely acts as a 5'-deoxyribose-5-phosphate lyase (5'-dRP lyase), catalyzing the beta-elimination of the 5'-deoxyribose-5-phosphate at abasic sites near DSBs. This activity cleans the termini of abasic sites, a common form of nucleotide damage, preparing broken ends for ligation (PubMed : 20383123). It may also possess 3'-5' DNA helicase activity, although this has not been confirmed in vivo, and its physiological significance remains unclear (PubMed : 7957065). Beyond DNA repair, the protein contributes to telomere maintenance (PubMed : 29490055). It is also implicated in transcriptional regulation, acting as a cofactor for various transcription factors (PubMed : 12145306, PubMed : 8621488). It 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). Can also bind RNAs and recruits PRKDC to a wide range of cellular RNAs, including the U3 small nucleolar RNA, playing a role in the biogenesis of ribosomal RNAs (PubMed : 32103174).
