Anti-SELENOK antibodies are used in the immunodetection of the protein selenoprotein K. In humans, the canonical protein has a reported length of 94 amino acid residues and a mass of 10.6 kDa. Its subcellular localization is in the ER and cell membrane. It is reported to be highly expressed in the heart. A member of the Selenoprotein K protein family, Selenok is known to be required for Ca(2+) flux in immune cells and plays a role in T-cell proliferation and in T-cell and neutrophil migration (By similarity). Post-translational modifications have been described, including ubiquitination and protein cleavage. SELENOK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Selenok antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
