Diseases associated with XRCC5 include Viral Exanthem and Werner Syndrome.Among its related pathways are Cytosolic sensors of pathogen-associated DNA and DNA damage_NHEJ mechanisms of DSBs repair.Gene Ontology (GO) annotations related to this gene include transcription regulatory region DNA binding. The Ku70/80 heterodimer protein plays a pivotal role in the NHEJ process. It possesses a ring-shaped structure with high affinity for DSBs and serves as the first responder and central scaffold around which the rest of the repair complex is assembled. KU70(-/-) and DNA-PKcs(-/-/-)chicken DT40 cells are reportedly highly sensitive to the DNA topoisomerase II inhibitor etoposide.

As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards. The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.

Man känner till ett tiotal proteiner som är involverade i dessa reparationsvägar, exempelvis Rad51, DNA-PK, Ku70/80, DNA-ligas IV, BRCA1 och BRCA2.

Taken together these results support the view that the core of all NHEJ complexes revolves around the Ku–XRCC4 interaction. Ku70-positive cells were present in 90.5% of tumours without and in 80% of tumours with lymphatic metastases. A similar relationship was found for Ku80 expression. paradoxical that Ku70/80, a protein that facilitates the joining of DNA ends, is localized at telomeres.

The Ku70/80 complex recognizes DNA breaks and serves as an essential hub for recruitment of NHEJ components. Here, we describe intramolecular … Nonhomologous end joining (NHEJ) is a DNA repair mechanism that religates double-strand DNA breaks to maintain genomic integrity during the entire cell cycle.

Further analysis however suggested that a likely explanation for these observations is that Ku70/80 plays distinct roles at pathological and natural DNA ends. Indeed, Ku70/80 has been proposed to perform at least two functions at telomeres.

In fact, the role of Ku70/80 proteins is highly complex and integrates different aspects of DNA repair. Eukaryotic Ku is a heterodimer of two polypeptides, Ku70 (XRCC6) and Ku80 (XRCC5), so named because the molecular weight of the human Ku proteins is around 70 kDa and 80 kDa.

Here, we describe intramolecular … Nonhomologous end joining (NHEJ) is a DNA repair mechanism that religates double-strand DNA breaks to maintain genomic integrity during the entire cell cycle.

Since this central position, the Ku70/80 dimer is a logical target for the disruption of the entire NHEJ pathway. Surprisingly, specific inhibitors of the Ku70/80 heterodimer are currently not available. During DNA double-strand break (DSB) repair, the ring-shaped Ku70/80 complex becomes trapped on DNA and needs to be actively extracted, but it has remained unclear what provides the required energy.
