The ELISA kits listed below target JAK3, the symbol for the human gene, Janus kinase 3, and a member of the Protein kinase superfamily, Tyr protein kinase family, JAK subfamily. The protein has an enzyme classification of protein-tyrosine kinase. The protein encoded by JAK3 has a predicted amino acid length of 1124, a mass of 125.1 kDa, and a cytoplasmic subcellular localization. There are currently 3 reported isoforms. Pathologic involvement is reported in Severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-negative. JAK3 may also be known by the following names: L-JAK, JAKL, JAK-3, leukocyte Janus kinase, Janus kinase 3 (a protein tyrosine kinase leukocyte), and tyrosine-protein kinase JAK3. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian are available targets of several ELISA kits.
