Abstract
The goals of this study were to identify specific mRNA for isoforms of calmodulin-dependent protein kinase II in chicken forebrain, prepare a cDNA expression library, and perform a sequence analysis of the kinase cDNA. Specific mRNAs for alpha- and beta-subunits of the kinase were identified in Northern blots. The mRNA for the alpha-subunit is larger in the chicken that in the rat, and for the beta-subunit is smaller in the chicken than the rat. Nucleotide sequencing of selected clones demonstrated the presence of an alpha-subunit with a 33 nucleotide insert known as the alpha-B-isoform. Clones of the beta-subunit showed it to contain a deletion of six nucleotides relative to previously described sequences. Variability in the mRNAs of calmodulin kinase II, as shown here, reflect the presence of species-dependent variability in gene structure as well as the presence of different functional isoforms.
