Identification of cdc2cAt: a new cyclin-dependent kinase expressed in Arabidopsis thaliana flowers

Biochim Biophys Acta. 1999 Jun 9;1445(3):351-8. doi: 10.1016/s0167-4781(99)00059-7.


In the present paper, the isolation of a third cyclin-dependent kinase gene and its cognate cDNA from Arabidopsis thaliana is described. Whereas other characterised cdc2 genes are ubiquitously expressed in Arabidopsis, expression of cdc2cAt is restricted to flowers. This gene, named cdc2cAt, differs from the two previously reported cdc2 genes in its organisation. Comparison with other cdc2 genes suggests that the deduced protein belongs to a new family of CDC2-like proteins related to the human CHED protein kinase.
