  • Product overview

    Phospho-JAK1 (Y1022/Y1023) + Total In-Cell ELISA Kit (Chemiluminescent) (ab207476) provides a simple, efficient, cell-based method to monitor proteins activated by phosphorylation. The kit is designed specifically to quantify activated (phosphorylated) JAK1 and/or total JAK1. Cells are cultured in 96-well plates and stimulated to induce the pathway of interest. Following stimulation, the cells are rapidly fixed to preserve activation-specific protein modifications. Each well is then incubated with a primary antibody that recognizes either phosphorylated JAK1 or total JAK1. Subsequent incubation with secondary HRP-conjugated antibody and chemiluminescent reagent provides an easily quantified chemiluminescent readout. The relative number of cells in each well is then determined using the provided Crystal Violet solution. The 96-well plate format is suitable for high-throughput screening applications.


    The Phospho-JAK1 (Y1022/Y1023) + Total In-Cell ELISA Kit (Chemiluminescent) (ab207476) contains 96-well plates and two primary antibodies. The phospho-JAK1 antibody was raised against a synthetic phospho-peptide corresponding to residues surrounding Tyr1022 and Tyr1023 of human JAK1. This antibody recognizes JAK1 only when phosphorylated at these sites and does not cross-react with related kinases. The total-JAK1 antibody recognizes JAK1 proteins regardless of the phosphorylation state.


    The kit can be used to study phosphorylated JAK1 relative to cell number or to determine JAK1 phosphorylation relative to the total JAK1 protein found in the cells. Once the phospho-JAK1 and total-JAK1 signals have been normalized for cell number, a comparison of the ratio of phosphorylated JAK1 to total JAK1 for each of the cell growth conditions can be made.

  • Notes

    Members of the JAK family of tyrosine kinases (JAK1, JAK2, JAK3 and Tyk2) are phosphorylated on multiple tyrosine residues after stimulation by cytokines, and in turn serve as docking sites for other signal-transducing proteins containing SH2 domains. JAK kinases play critical roles in the pathogenesis of various human neoplastic diseases. They have been shown to modulate activation of Ras-Raf-MAP kinase pathways and are also involved in interferon-signaling. In addition, JAK kinases promote malignant cell survival and growth by modulating apoptosis via regulation of the Bcl-2 family members Bcl-XL, Bcl-2 and Bax. Bcl-2 regulation is independent from JAK kinase effects on STATs and other receptor linked pathways such as the PI3K and the Ras-MAPK.

    JAK1 (Janus Kinase 1) is a 130 kDa non-receptor protein tyrosine kinase. JAK1 is a widely expressed, membrane-associated kinase involved in many signal transduction pathways including those involving interferon α, β and γ, all class II receptors and cytokine receptors that utilize the common γ chain or gp130 subunit. JAK1 can be activated via phosphorylation on tyrosines 1022 and 1023 in the kinase activation loop. Once activated, JAK1 phosphorylates STAT proteins and SHP2. Phosphorylated STATs then dimerize and translocate to the nucleus. Once in the nucleus, STAT proteins bind to DNA and modify the transcription of various genes, which leads to various responses such as cell proliferation, cell survival and differentiation.

  • Function

    Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway. Kinase partner for the interleukin (IL)-2 receptor.
  • Tissue specificity

    Expressed at higher levels in primary colon tumors than in normal colon tissue. The expression level in metastatic colon tumors is comparable to the expression level in normal colon tissue.
  • Sequence similarities

    Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
    Contains 1 FERM domain.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.
  • Domain

    Possesses 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.
    The FERM domain mediates interaction with JAKMIP1.
  • Cellular localization

    Endomembrane system. Wholly intracellular, possibly membrane associated.
