Anti-JRK antibodies are used in the immunodetection of the protein Jrk helix-turn-helix protein. In humans, the canonical protein has a reported length of 556 amino acid residues and a mass of 61.8 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Tigger transposable element derived protein family, JRK is believed to bind DNA. Synonyms for this target antigen include jerky, jerky protein homolog, Jrk homolog, jerky homolog, and JH8. JRK gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. ELISA, Western Blot, Immunocytochemistry, and Immunofluorescence are common applications for JRK antibodies.
