  • Function

    Responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating a number of transcription factors, primarily components of AP-1 such as c-Jun and ATF2 and thus regulates AP-1 transcriptional activity. In T-cells, JNK1 and JNK2 are required for polarized differentiation of T-helper cells into Th1 cells.
    JNK2 isoforms display different binding patterns: alpha-1 and alpha-2 preferentially bind to c-Jun, whereas beta-1 and beta-2 bind to ATF2. However, there is no correlation between binding and phosphorylation, which is achieved at about the same efficiency by all isoforms. JUNB is not a substrate for JNK2 alpha-2, and JUND binds only weakly to it.
  • Sequence similarities

    Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
    Contains 1 protein kinase domain.
  • Domain

    The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
  • Post-translational

    Dually phosphorylated on Thr-183 and Tyr-185, which activates the enzyme. Autophosphorylated in vitro.

Customer reviews and Q&As


Thank you for contacting Abcam with your questions pertaining to ab119726. I have been in contact with the laboratory about the questions that you have raised. The tag used in this preparation is GST. ab1198726 may be used in conjunction with cell study as it is highly likely that it provides cell permeability. It would depend on how you would transfer it into the cell. Currently there is no specific protocol for a functional study with this protein. Please do not hesitate to contact us if there is anything else that we might do to help you achieve you research goals.
