According to the similarity of the amino acid sequences in their catalytic domains, eukaryotic protein kinases have been classified into the five main groups: ‘AGC’, ‘CaMK’, ‘CMGC’, ‘PTK’ and ‘other’. The AGC group, represented by the cyclic nucleotide-dependent kinases (PKA and PKG), the calcium-phospholipid-dependent kinases (PKC) and the ribosomal S6 protein kinases, are poorly characterized in plants except for a few cases. In this study, in order to gain a better understanding of plant protein kinases in the AGC group, three cDNAs encoding novel protein kinases, RsNdr1 and RsNdr2a/b, were cloned from radish and characterized by molecular and biochemical methods.<br> The deduced amino acid sequences of RsNdr1 and RsNdr2a/b contained all 12 conserved catalytic subdomains which are characteristic of the eukaryotic Ser/Thr protein kinases. A cell lysate from E. coli overexpressing RsNdr1 fusion protein had protein kinase activity toward a conventional protein substrate (myelin basic protein), whereas that from E. coli harboring a fusion plasmid encoding kinase-dead RsNdr1 or RsNdr2 did not show any protein kinase activity. A phylogenetic tree for 17 protein kinases from various organisms showed that the RsNdrs are more closely related to the protein kinases in a particular subgroup of the ‘AGC’ (fungal cot1-like and animal Ndr kinases) than to the authentic ‘AGC’ protein kinases, such as PKA, PKC or ribosomal S6 kinase.<br>
