Background/Aims: The kinases SPAK (SPS1-related proline/alanine-rich kinase) and OSR1 (oxidative stress-responsive kinase 1) participate in the regulation of the NaCl cotransporter NCC and the Na+. K+. 2Cl- cotransporter NKCC2. The kinases are regulated by WNK (with-no-K[Lys]) kinases. https://www.cosmeticssquadets.shop/product-category/food-items/
