  • Function

    This is a calcium-independent, phospholipid-dependent, serine- and threonine-specific enzyme. Essential for T-cell receptor (TCR)-mediated T-cell activation, but is dispensable during TCR-dependent thymocyte development. Links the TCR signaling complex to the activation of NF-kappa-B in mature T lymphocytes. Required for interleukin-2 (IL2) production.
    PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters.
  • Tissue specificity

    Skeletal muscle, megakaryoblastic cells and platelets.
  • Sequence similarities

    Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily.
    Contains 1 AGC-kinase C-terminal domain.
    Contains 1 C2 domain.
    Contains 2 phorbol-ester/DAG-type zinc fingers.
    Contains 1 protein kinase domain.
  • Domain

    The C1 domain, containing the phorbol ester/DAG-type region 1 (C1A) and 2 (C1B), is the diacylglycerol sensor and the C2 domain is a non-calcium binding domain.
  • Post-translational

    Autophosphorylation at Thr-219 is required for targeting to the TCR and cellular function of PKC upon antigen receptor ligation.

Customer reviews and Q&As


Thank you for your enquiry.

In this case I would suggest using acapture ELISA assay. Here, the capture antibody will be an antibodyto capture total PKC theta and thedetection antibody will be yourab63365. For the capture antibody you can try https://www.abcam.com/PKC-theta-antibody-ab4133.html, although this has not yetbeen tested as capture antibody.

Then you'll need a secondary antibody, conjugated to an enzyme for example, to detect this detection antibody. One example of a secondary antibody you could use is https://www.abcam.com/Rabbit-IgG-secondary-antibody-H-L-Pre-Adsorbed-ab7083.html

For apositive control/standard curve, you canuse our recombinant full length PKC theta protein, https://www.abcam.com/PKC-theta-protein-Tagged-ab56641.html

I hope this is helpful. Please contact me again if you have any further questions.
