Raft localized PKC theta is further phosphorylated and activated by PDK1. The threonine residue (T538) in the kinase domain is the potential target of PDK1. Phosphorylation of this site is critical for the PKC theta kinase activity, and its ability to activate NF-kB pathway. PKC theta is later trans-autophopshorylated on putative phosphorylation sites (S676, S695) for the fine-tuning of its kinase activity.
