Anti-DGKK antibodies are used in the immunodetection of the protein diacylglycerol kinase kappa. In humans, the canonical protein has a reported length of 1271 amino acid residues and a mass of 141.8 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in the testis, and to a lesser extent in the placenta. A member of the Eukaryotic diacylglycerol kinase protein family, DGKK is reported to be a diacylglycerol kinase that converts diacylglycerol/DAG into phosphatidic acid/phosphatidate/PA and regulates the respective levels of these two bioactive lipids. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include DAG kinase kappa, DGK-kappa, diglyceride kinase kappa, and 142 kDa diacylglycerol kinase. DGKK gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Immunofluorescence is the most common application for the DGKK antibodies listed below. ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
