Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 125 kDa (predicted molecular weight: 125 kDa).


  • FunctionTyrosine kinase of the non-receptor type, involved in the interleukin-2 and interleukin-4 signaling pathway. Phosphorylates STAT6, IRS1, IRS2 and PI3K.
  • Tissue specificityIn NK cells and an NK-like cell line but not in resting T-cells or in other tissues. The S-form is more commonly seen in hematopoietic lines, whereas the B-form is detected in cells both of hematopoietic and epithelial origins.
  • Involvement in diseaseDefects in JAK3 are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-negative (T(-)B(+)NK(-) SCID) [MIM:600802]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
    Contains 1 FERM domain.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.
  • DomainPossesses two phosphotransferase domains. The second one probably contains the catalytic domain (By similarity), while the presence of slight differences suggest a different role for domain 1.
  • Post-translational
    Tyrosine phosphorylated in response to IL-2 and IL-4.
  • Cellular localizationEndomembrane system. Wholly intracellular, possibly membrane associated.

  • Anti-JAK3 antibody (ab125296) at 1 µg/ml (Milk blocking - 1%) + TF-1 (Human erythroleukaemic cell line) Whole Cell Lysate at 25 µg

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 125 kDa
    Observed band size : 125 kDa

    Exposure time : 8 minutes

    This blot was produced using a 10% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 1% Milk before being incubated with ab125296 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
