Ku70

Ku70 and Ku80 are part of a high‐affinity heterodimeric protein complex, known as Ku (19, 27). The Ku heterodimer binds nonspecifically to DNA ends with high affinity (K d: 1–2 nM) , and FOXO4 contains a DNA binding domain required for binding Forkhead sites on DNA . 2012-06-29 · The KU70 flipper knock-out cassette was constructed with 1299bp 5′ and 1170bp 3′ flanking sequences from the KU70 locus. Both integration sequences were placed partially on top of the coding sequence, so that the deletion caused by the knock-out cassette integration would be only 215bp.

Ku70

From: International Review of Cell and Molecular Biology, 2019 Ku-core domain, Ku70 subfamily; Ku70 is a subunit of the Ku protein, which plays a key role in multiple nuclear processes such as DNA repair, chromosome maintenance, transcription regulation, and V(D)J recombination. Ku70 is required for late B cell development and immunoglobulin heavy chain class switching Immunoglobulin (Ig) heavy chain (HC) class switch recombination (CSR) is a late B cell process that involves intrachromosomal DNA rearrangement. 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. The two Ku subunits form a basket-shaped structure that threads onto the DNA end. Heterodimers of the 70 and 80 kDa Ku autoantigens (Ku70 and Ku80) activate the DNA‐dependent protein kinase (DNA‐PK).

I de fallen ska royaltyn alltid redovisas på KU70. Ku70 and Ku80 make up the Ku70/80 heterodimer. They are encoded by the Xrcc5 and Xrcc6 genes, respectively, and are highly abundant in both prokaryotes and eukaryotes.

XRCC6 (X-Ray Repair Cross Complementing 6) is a Protein Coding gene. Diseases associated with XRCC6 include Lupus Erythematosus and Nijmegen Breakage 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 protein C-terminus binding. ku70 tert : gl1; ku70; tert: images; None available : phenotypes ; Surovtseva YV, Shakirov EV, Vespa L, Osbun N, Song X, Shippen DE(2007) In contrast to the ku70 mutant, which undergo telomerase-dependent expansion to more than twice the normal length in a single generation, the ku70 tert double mutant displays accelerated telomere shortening and a precocious onset of genome stability.

The dimer associates in a DNA-dependent manner with PRKDC to form the DNA-dependent protein kinase complex DNA-PK, and with the LIG4-XRCC4 complex to form the core of the non-homologous end joining (NHEJ) complex. The Ku70‐specific C‐terminal region consists of a 5 kDa SAP domain (Ku70‐SAP), the structure of which was determined both in isolation (Zhang et al, 2001) and as part of the Ku70–Ku80 crystal structure (Walker et al, 2001; Fig 1C). Ku antigen is a complex of Ku70 and Ku80 subunits and plays an important role in not only DNA double-strand breaks (DSB) repair and V(D)J recombination, but also in growth regulation. Ku is Knockdown of Ku70 was achieved by transfecting HeLa with Ku70 specific siRNAs (Silencer® select Product # S5455, S5457). Western blot analysis (Fig.

The stability of these proteins depends on each other. Ku70 is an evolutionarily conserved protein that has functions in DNA repair and maintenance [96].

Ku antigen is a complex of Ku70 and Ku80 subunits and plays an important role in not only DNA double-strand breaks (DSB) repair and V(D)J recombination, but also in growth regulation. Ku is Knockdown of Ku70 was achieved by transfecting HeLa with Ku70 specific siRNAs (Silencer® select Product # S5455, S5457). Western blot analysis (Fig. a) was performed using Nuclear enriched extracts from the Ku70 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). 2002-12-06 · Human Ku70/80 associates physically with telomerase through interaction with hTERT.

We (unpublished data) and others [43] had evaluated and shown that proteins involved in DNA repair including DNA-PK, p53, ATM and Ku70 had no effect on the type-I-IFN response induced by cytosolic dsDNA stimulation.

The Ku70 NLS contains five lysines (K539, K542, K544, K553 and K556) that were identified as targets for acetylation in vivo. 18, 29 Lysine acetylation in the cytoplasm drives and coordinates key events such as cytoskeleton dynamics, intracellular trafficking, vesicle fusion, metabolism and stress response. 43, 44 We hypothesized that acetylation of the five lysine residues in the Ku70 NLS 2001-03-01 · Ku70:Ku80 complex Source: GO_Central "Phylogenetic-based propagation of functional annotations within the Gene Ontology consortium."
