Protein kinase C: is its pivotal role in cellular activation over-stated?

Author information

  • 1Roche Research Centre, Herts, UK.


Evidence has emerged over the past decade to suggest that protein kinase C (PKC) is a widespread family of kinases responsible for many diverse and critical cellular functions. With the development of selective agents to activate or inhibit the individual PKC isoenzymes, it is now apparent that much of the literature that implicated PKC in many cellular functions needs to be appraised. In this article, Sandra Wilkinson and Trevor Hallam discuss the problems of the existing methods and the recent evidence that suggests that PKC isotypes are necessary for some, but not all, of those cellular responses where PKC had been thought to play an important role. Selective inhibitors of PKC isoenzymes may have potential for therapeutic use in auto-immune diseases, transplant rejection and oncology.
