Protein kinases (PKs) play critical roles in signal transduction and activation of lymphocytes. The identification of PK genes provides a tool for understanding mechanisms of immunotoxic xenobiotics. As part of a larger study investigating persistent organic pollutants in the harbor seal and their possible immunomodulatory actions. we sequenced harbor seal cDNA fragments encoding PKs. https://herbsdailyes.shop/product-category/borage-oil/
