Using ATP as a phosphate donor, NADK catalyzes the phosphorylation of NAD to NADP . This molecule is then reduced to NADPH and utilized in various metabolic and biosynthetic pathways (2). NADK has been suggested to play a role in glucose metabolism due to the effect NADPH production has on both the insulin secretion and survival of pancreatic Î²-cells (3). NADPH has a vital role in protecting cells from oxidative stress through its neutralizing effect on reactive oxygen species (ROS), which also accumulate during cell growth (2-4). Along with the p53 tumor suppression protein, NADK has been a suggested target in cancer therapy due to its link to NADPH production and its resulting protective role on growing and proliferating cells (2). Cytoplasmic NADK isoform 3 is transcribed from a unique start site compared to isoforms 1 and 2, and lacks the N-terminal, Akt-dependent, activating phosphorylation sites of Ser44, Ser46, and Ser48 found in the other isoforms (5). Cells engineered to exclusively express NADK isoform 3 exhibit constitutively increased NAD kinase activity, insensitivity to AKT agonists, and increased synthesis of NADP (5). NADK isoform 3 is uniquely upregulated in metastatic nodules of a PDX model of melanoma (6). Isoform 3 expression is driven by transcription factor NRF2 in response to oxidative stress, allowing melanoma cells to survive both oxidative insult and metastatic cascade by increasing NADP synthesis (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\ndJ283E3.1; NAD kinase\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 52\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799898542249,"sku":"76851S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-76851s","provider":"Iright","version":"1.0","type":"link"}
