The primary structure of the neuronal Type II calmodulin-dependent protein kinase has been examined by protein sequence analysis and compared to cDNA-derived sequence . Tandem mass spectroscopic analysis was used for the sequence determination. Comparison with published cDNA sequence data for the alpha subunit revealed that the difference between the alpha- and beta-subunits lay in two insertions into the sequence for the alpha-subunit and a short alpha-specific sequence. The N-terminal amino acid of the alpha subunit which is blocked to Edman degradation has been tentatively identified as N-acetyl-alanine.
