Anti-EIF2AK2 antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 2 alpha kinase 2. In humans, the canonical protein has a reported length of 551 amino acid residues and a mass of 62.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in thymus, spleen and bone marrow compared to non-hematopoietic tissues such as small intestine, liver, or kidney tissues. A member of the Ser/Thr protein kinase protein family, EIF2AK2 is known to be involved with viral immune response and the regulation of apoptosis. Synonyms for this target antigen include EIF2AK1, LEUDEN, PKR, PPP1R83, PRKR, and DYT33. EIF2AK2 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Over 250 citations in the literature describe the use of EIF2AK2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
