Description
The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Rat Fc gamma RIIB/CD32b is immobilized on an anti-His Tag Antibody coated plate, it binds Biotinylated Rat IgG. The concentration of Biotinylated Rat IgG that produces 50% of the optimal binding response is 0.5-3 μg/mL.
Storage
