The protein kinase C family (PKC) comprises ~2% of the human kinome and can be subdivided into three subclasses: conventional or classical (cPKC), novel (nPKC) and atypical (aPKC). All isoforms contain a C-terminal kinase domain and an N-terminal autoinhibitory pseudosubstrate but differ in their responsiveness to second messengers. A tandem DAG-sensitive C1 domain is present in cPKC and nPKC with the latter group displaying a higher sensitivity. The C2 domain is Ca2+ sensitive in cPKC only. The
