The RBPJK ELISA kits listed below are analytical tools for measuring concentrations of RBPJK in various samples. RBPJK is an alternative name for the human RBPJ gene, which encodes the protein, recombination signal binding protein for immunoglobulin kappa J region. It has been mentioned that RBPJK plays a role in angiogenesis and B cell differentiation, among other functions. Structurally, the RBPJ protein is 500 amino acid residues in length and 55.6 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include AOS3, CBF-1, and CBF1.
