Anti-Inhibitor of Bruton tyrosine kinase antibodies are available from several suppliers. In humans, this protein is encoded by the gene IBTK. The protein may also be known as BTKI, BTBD26, BTK-binding protein, and Bruton agammaglobulinemia tyrosine kinase inhibitor. The expected protein mass is 150.5 kDa, but there are 3 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine, monkey, mouse and rat.
