{"product_id":"cst-6389s","title":"CST,  6389S, SignalSilence® CK2 alpha siRNA I","description":"siRNA for studying CK2A1 in the research area.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nCST recommends transfection with 100 nM SignalSilence ® CK2 alpha siRNA I 48 to 72 hours prior to cell lysis. For transfection procedure, follow protocol provided by the transfection reagent manufacturer. Please feel free to contact CST with any questions on use. Each vial contains the equivalent of 100 transfections, which corresponds to a final siRNA concentration of 100 nM per transfection in a 24-well plate with a total volume of 300 μl per well.\n\u003cb\u003eStorage\u003c\/b\u003e\nSignalSilence ® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.\n\u003cb\u003eBackground\u003c\/b\u003e\nCK2 (formerly called Casein Kinase II) is a highly conserved protein kinase with more than 300 substrates regulating cell growth, cell death, and cell survival. CK2 has been implicated in the response to UV irradiation-induced DNA damage, targeting XRCC1 (1) and BRCA1 (2) as well as regulating p53 tumor suppressor protein functions (3). Furthermore, CK2 plays a key role in NF-κB activation (4). UV irradiation stimulates CK2-mediated phosphorylation of several carboxy-terminal residues within IκBα, resulting in IκBα proteasomal degradation and the release and nuclear translocation of active NF-κB. CK2 is also dysregulated in many cancers (5) and neurodegenerative diseases such as Alzheimer's and Parkinson's diseases (6). Structurally, CK2 is a multimeric protein complex consisting of two catalytic subunits (α or α') and two regulatory β subunits (7). CK2 is distributed ubiquitously and is apparently constitutively active (7). While cell cycle-dependent Ser-Pro phosphorylation sites have been identified on CK2α and CK2β, Tyr255 phosphorylation by the Src-related kinase c-Fgr seems to have the greatest effect on CK2α activity (8,9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCK2-α\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H","brand":"CST","offers":[{"title":"Default Title","offer_id":46800789602473,"sku":"6389S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-6389s","provider":"Iright","version":"1.0","type":"link"}
