Ku protein
The Ku heterodimer provides DNA-binding and regulatory functions to DNA-dependent protein kinase which is a central enzyme for DNA recombination processes in eucaryotic cells. The Ku protein plays important roles in multiple nuclear processes including DNA repair, V(D)J recombination, telomere maintenance, and the regulation of specific gene ...Ku was demonstrated to be a component of the DNA-dependent protein kinase (DNA-PK) complex, which is a nuclear serine/threonine protein kinase (Lees-Miller et al., 1990; Gottlieb et al., 1993).The Ku heterodimer provides DNA-binding and regulatory functions to DNA-dependent protein kinase which is a central enzyme for DNA recombination processes in eucaryotic cells. The Ku protein plays important roles in multiple nuclear processes including DNA repair, V(D)J recombination, telomere maintenance, and the regulation of specific gene ...

This means that a 1 mg/ml solution of the protein will have an absorbance at 280 nm of 0.54. E (0.1%, 280) can be used as a very convenient measure of the protein content provided that the enzyme preparation supplied by Sigma is pure. A 'rule of thumb', useful when the E (0.1%, 280) is unknown, is that a 1mg/ml protein solution has an A280 of 1.Unlike E. coli, Mycobacterium tuberculosis (Mt) expresses a Ku-like protein and an ATP-dependent DNA ligase that can perform non-homologous end-joining (NHEJ). We have expressed the Mt-Ku and Mt-Ligase D in E. coli using an arabinose-inducible promoter and expression vectors that integrate into specific sites in the E. coli chromosome.E. coli strains have been generated that express the Mt-Ku ...Benzonase® Nuclease HC, Purity >99% 25 KU 71206-3 Benzonase® Nuclease, Purity >90% 2.5 KU 10 KU 70746-4 70746-3 Benzonase® Nuclease HC, Purity >90% 25 KU 71205-3 Ideal for a variety of applications ... Protein Extraction Reagent and the other half was lysed with BugBuster plus Benzonase® Nuclease following the recommend protocol.
Europe PMC is an archive of life sciences journal literature. Search life-sciences literature (41,454,239 (41,454,239All patients had very high titer of ANA with speckled and nucleolar pattern. All the sera were positive for anti-Ku antibodies by CIE: all but one were confirmed by IB. Eight sera contained isolated antibodies to Ku proteins: both subunits were recognized in 7 cases, while isolate reactivity to the 70 kDa protein was detected in one case.Function. Together, Ku70 and Ku80 make up the Ku heterodimer, which binds to DNA double-strand break ends and is required for the non-homologous end joining (NHEJ) pathway of DNA repair. It is also required for V (D)J recombination, which utilizes the NHEJ pathway to promote antigen diversity in the mammalian immune system .Services Offered: Protein construct design, expression and purification for crystallization (gene-to-structure) Protein crystallization (only 12 mL of protein needed per 96-well screen) High throughput methods using robotics for crystallization and crystal imaging. Screening of protein ligand, inhibitor complexes and protein:protein complexes. They used a colorectal cancer cell line engineered with this deficiency, which gradually knocked out the Ku70 protein, resulting in depletion of both parts of the Ku complex, Ku70 and Ku86. They then studied the movement of these Ku-deficient cancer cells under a microscope and compared their activity to parental cancer cells with their …

Ku serves as the DNA-binding subunit of the DNA-dependent kinase and is a heterodimeric protein composed of 80- and 70-kDa subunits. We used the two-hybrid system to analyze the interaction ...
KU80; Ku-core domain, Ku80 subfamily; Ku80 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. The mechanism underlying the ... pfam08785. Location:558 → 672.Ku80, a subunit of the Ku protein complex, is an initiator of the non-homologous, end-joining (NHEJ), double-strand breaks (DSBs) repair pathway. The nuclear Ku80 was cleaved in a calcium concentration-dependent manner by m-calpain but not by m-calpain. The cleavage of nuclear Ku80 at its α/β domain was validated by Western blotting analysis ...Oxidative stress induces DNA damage which can be repaired by DNA repair proteins, such as Ku70/80. Excess reactive oxygen species (ROS) stimulate the activation of caspase-3, which degrades Ku 70/80. Cells with decreased Ku protein levels undergo apoptosis. Astaxanthin exerts antioxidant activity by inducing the expression of catalase, an antioxidant enzyme, in gastric epithelial cells ...

Location:558 → 672. bachelor's in sport management Here, the double-strand breaks are primarily detected by Ku protein (Ku70-Ku80 heterodimer) [117], which then recruits the DNA protein kinase catalytic subunits (DNA-PKcs), forming Ku-DNA-PK complex surrounding the broken strands. When a double-strand break occurs, the configuration at the broken ends can vary. They can have blunt ends, 5 ... thomas hegnawashington works dupontkansas state 2012 football schedule May 26, 2013 · These results suggest that Ku proteins are specific to breast cancer progression and indicate that in intestinal cancer cells, tumoregenesis is not associated with Ku protein expression. Many studies have suggested a key role of Ku in cancer development and progression, acting as either tumor suppressor gene or as oncogene 45 . zillow overgaard az In this study, recombinant Pichia pastoris was constructed for malic acid production from sole methanol through rational redistribution of metabolic flux.
