title: Molecular cloning of the cDNA encoding the third polypeptide (gamma) of brain calmodulin-dependent protein kinase II.
abstract: cDNA clones for three distinct types of rat brain calmodulin-dependent protein kinase II have been isolated. Two of them were identified as cDNA clones for the alpha and beta subunits of this kinase. The other showed a nucleotide sequence similar but, not identical, to that encoding either the alpha or beta subunit. The cDNA sequence encoded a polypeptide, designated gamma, consisting of 527 amino acid residues with a molecular weight of 59,038. The deduced amino acid sequence of gamma was 84 and 87% homologous to those of alpha and beta, respectively. Higher homologies of the sequences were found in the amino-terminal halves of the three species, alpha, beta, and gamma. RNA blot analysis revealed that the mRNAs for alpha, beta, and gamma were expressed in rat brain with different regional specificities.
