Sep 9, 2021 · A deep chemical proteomic investigation of diverse aminophilic electrophiles has identified ligandable lysines across a wide range of human proteins. The proteins cover different functional and ...Ku protein and the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) are essential components of the double-strand break repair machinery in higher eukaryotic cells. Ku protein binds to broken DNA ends and recruits DNA-PKcs to form an enzymatically active complex. To characterize the arrangement of proteins in this complex, we developed ...The DNA-binding protein Ku plays a critical role in a variety of cellular processes, including the repair of double-stranded DNA breaks and V (D)J recombination. Paradoxically, while Ku is required for double-stranded break repair by non-homologous end-joining, in many organisms, Ku is also associated with telomeres.Nomenclature Ku80 has been referred to by several names including: Lupus Ku autoantigen protein p80 ATP-dependent DNA helicase 2 subunit 2 X-ray repair complementing defective repair in Chinese hamster cells 5 X-ray repair cross-complementing 5 (XRCC5) Epigenetic repression

DNA double strand break (DSB) repair by non-homologous end joining (NHEJ) is initiated by DSB detection by Ku70/80. (Ku) and DNA-dependent protein kinase ...The current thinking is that Ku protein binds to DNA discontinuously and in a sequence independent manner, carrying out a DNA-protective role . Once bound to DNA, Ku proteins recruit and activate the catalytic DNAPKcs subunit which can phosphorylate Ku and other neighboring DNA-bound proteins . It has also been reported that DNAPKcs self ...Then the Ku heterodimer recruits to the DSB the catalytic subunit of DNA-dependent protein kinase DNA-PKcs (gene PRKDC). Altogether, Ku70, Ku80, and DNA-PKcs form a DNA-dependent protein kinase holoenzyme (DNA-PK), which protects and holds together two ends of the broken DNA, and serves as a scaffold for other proteins of the cNHEJ pathway (e.g ...In this study, we further explored the protein components of the TCF-4 and β-catenin nuclear complex and identified that Ku70 and Ku80 proteins interact with TCF-4. The Ku autoantigen was originally identified as a nuclear protein recognized by autoantibodies in sera of patients with polymyositis-scleroderma overlap syndrome . The Ku ...

[PubMed] [DOI]. 8 ...derived from scid mice [22] as well as Ku deficient mice [2, 20]. Ku protein is involved in the same repair pathway affected in scid mice (see below). Since telomere length is maintained within a specific range in each species, the mechanisms for telomere length regulation must have evolved to maintain this homeostasis. Proteins that bind telom­ ….

The DNA-dependent protein kinase: requirement for DNA ends and association with Ku antigen. Cell 72 , 131-142 (1993). Article CAS PubMed Google ScholarAlthough all structural studies of DNA-PK contain the same full-length DNA-PKcs, different constructs of Ku protein are used in the complexes defined by X-ray and cryo-EM studies. The X-ray structure of DNA-PK contains Ku80CTR (Sibanda et al., 2017), while two cryo-EM studies contain full length Ku70/80 (Sharif et al., 2017; Yin et al., 2017 ...Ku binds the broken DNA end and recruits other proteins to facilitate the processing and ligation of the broken end. While Ku interacts with many proteins involved in DNA damage/repair-related functions, few interactions have been mapped to the N-terminal von Willebrand A (vWA) domain, a predicted protein interaction domain.

DNA-PK is thought to act as the "sensor" for DNA double-stranded breaks (DSB), which are considered the most deleterious type of DNA damage. In particular, DNA-PKcs and Ku are shown to be essential for DSB repair through nonhomologous end joining ... who does ku play next Bagikan.
