Tissue-specific expression of three distinct types of rabbit protein kinase C.
We examined the structure of protein kinase C in an attempt to understand the molecular events connecting protein kinase C activation with the cellular response. Rabbit complementary DNA clones coding for three distinct types of protein kinase C, named alpha, beta and gamma, have been identified and sequenced. The deduced amino acid sequence for alpha, beta and gamma (673, 671 and 672 amino acids, respectively) are closely related. Kinases alpha and beta share an identical N-terminal sequence of 621 amino acid residues and their messenger RNAs arise from a single gene. The C-terminal halves of alpha, beta and gamma are protein kinase domains and are highly homologous to other protein kinases. The mRNAs for alpha, beta and gamma are expressed in various tissues with strikingly different tissue specificities. The one for gamma is found ubiquitously among various tissues, while those for alpha and beta predominate in the brain.
