  • 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.

I did check with the lab regarding the protocol used, the cells should be serum starved before PMA treatment and the concentration is 200nM.
