Anti-casein kinase 2 beta antibodies are used for the immunodetection of the protein encoded by the CSNK2B gene. In humans, the canonical protein has a reported length of 215 amino acid residues and a mass of 24.9 kDa. A member of the Casein kinase 2 subunit beta protein family, it is a regulatory subunit of casein kinase II/CK2. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Poirier-Bienvenu neurodevelopmental syndrome. Other names for this target antigen include CK2N, CSK2B, Ckb1, Ckb2, G5A, POBINDS, casein kinase II subunit beta, and CK2B. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of casein kinase 2 beta antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
