A central nervous system (CNS) cell line, CAD, is known to differentiate in the absence of serum. This cell line was found to differentiate by the treatment of cAMP. Expression of Ca(2+)/calmodulin-dependent protein kinase II (CaM kinase II) was induced to about 2-fold or more on day 1, and was continued at a high level for 5 days after the exposure to differentiating conditions. Neurite extension was stimulated from day 1 and continued for 5 days, suggesting that CaM kinase II activity is correlated with neurite outgrowth. Of the four distinct isoforms (alpha, beta, gamma, and delta) of the kinase, the delta isoform was the major isoform in CAD cells. The splicing pattern of this isoform in the differentiated cells differed from that in undifferentiated cells, suggesting that expression of CaM kinase II is regulated during neural differentiation.

The 5' flanking region of the alpha isoform of the rat Ca2+/calmodulin-dependent protein kinase II (alpha CaM kinase II) gene was isolated in 2.3 kbp of genomic sequence. Functional analysis of alpha CaM kinase II promoter deletion mutants fused to a reporter gene in neuroblastoma, including N18TG2, NG108-15, and CAD cells revealed strong transcriptional activity localized 100-145 bp, and a potent silencer 199-275 bp upstream of the transcription start site. The promoter is inactive in non-neuronal cells including BALB/c 3T3, Chinese hamster ovary, HT1080, and C6 glioma cells. These results indicated that the alpha CaM kinase II gene is transcribed from a tissue-specific promoter which is under intense negative control.
