Scientific Background: PKCt (PKCq, PRKCT, PKC-theta) is a protein-serine/threonine kinase of the AGC group and novel PKC family. It is dependent on acidic phospholipids (e.g. phosphatidylserine) and diacylglycerol for full phosphotransferase activity, and does not require calcium. It is essential in TCR signalling for T-cell activation, differentiation, proliferation, and survival. These T-cell responses are mediated via Jun, NF-kappa-B, NFATC1 and NFATC2. The phosphotransferase activity of PKCt is unaffected by an Y90F mutation, but T-cell proliferation is inhibited. An A148E mutation results in constitutive activation of PKCt. A T219A mutation again will not inhibit kinase phosphotransferase activity, but it will inhibit localization to the plasma membrane and inhibit transactivation of IL2 promoter. Phosphorylation at Y90, T538 (activation loop of the kinase domain) and S676 (turn motif) increases phosphotransferase activity. Phosphorylation at S695 (hydrophobic region) increases phosphotransferase activity and interaction with PDK1. Insertional mutagenesis studies in mice support a role for this protein kinase in mouse cancer oncogenesis. PKCt is linked to Gastrointestinal Stromal Tumours (GANT, GIST), which are rare sarcomas arising from tissues lining the gastrointestinal tract and typically arise from the stomach, intestines, or colon. GANT has been related to neurofibromatosis and adenocarcinoma as well.
