Anti-RIOK2 antibodies are used in the immunodetection of the protein RIO kinase 2. In humans, the canonical protein has a reported length of 552 amino acid residues and a mass of 63.3 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the RIO-type Ser/Thr kinase protein family, RIOK2 is known to be a protein kinase involved in the final steps of cytoplasmic maturation of the 40S ribosomal subunit. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include serine/threonine-protein kinase RIO2. RIOK2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RIOK2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
