PKC-θ in T Cell Signaling:
The expression and phosphorylation of PKC isoforms are intricately regulated by various kinases, including PDK1. This regulation is crucial for the stability, localization, and functional specificity of PKC isoforms. Different PKC isoforms exhibit unique substrate specificities and play distinct roles in cellular processes such as NADPH oxidase activation, glutamine synthetase expression, cell cycle regulation, and T cell signaling. Understanding these mechanisms provides valuable insights into the diverse functions of PKC in cellular physiology.
