The authors cloned a novel, brain-specific, Ca/calmodulin-dependent protein kinase from a rat lambda gt11 library which was probed for calmodulin-binding proteins. Antibodies raised against the b-galactosidase fusion protein recognized Mr 65000 and Mr 65000/67000 polypeptides from rat forebrain and cerebellum, respectively. Both polypeptides co-purified to homogeneity and phosphorylated synapsin I. The protein kinase is coded for by two poly A+RNAs at 2.0 kb and 3.5 kb which probably derive from a single gene. A 1.3 kbp cDNA insert contained 477 bp of protein coding sequence which included a calmodulin-binding domain, but no further sequence similarities to other protein kinases. Immunohistochemical localization with a monospecific antibody revealed that the enzyme was expressed in specific subpopulations and was exceptionally enriched in the granule cells of the cerebellum.
