Abstract
The cdc2 protein kinase plays a key role in controlling the eukaryotic cell cycle. We have isolated a cDNA clone for the chicken homolog of the cdc2 gene, raised antibodies against the corresponding protein, and studied the expression of cdc2 mRNA and protein during chicken embryonic development. The protein encoded by the chicken cdc2 cDNA shares extensive structural homology with cdc2 gene products from other species. Moreover, when expressed in fission yeast, the chicken cdc2 kinase is able to rescue a temperature-sensitive (ts) cdc2 mutant, demonstrating that it is functional as a cell cycle regulator. By Northern analysis and immunoblotting, we found that in total embryos both cdc2 mRNA and protein levels decreased substantially between day 3 and day 11 after egg laying, and no significant amounts of either cdc2 mRNA or protein were detected in adult liver, brain, heart or skeletal muscle. These data indicate the existence of a coarse correlation between the abundance of cdc2 mRNA and the proliferative state of a given tissue. Interestingly, however, when examining individual embryonic tissues, no correlation was observed between levels of cdc2 mRNA and protein, suggesting that cdc2 expression in developing chicken may be regulated at multiple levels.
