From: Phylogenetic analysis of CDK and cyclin proteins in premetazoan lineages
Schematic representation of the distribution of different CDK subfamilies in eukaryotic organisms. The results of phylogenetic analyses of CDK family proteins in different organisms are summarized. A black dot indicates the presence of clear homologs of CDK subfamilies or clades (see text for further explanations). Phylogenetic relationships of these organisms are based on recent reports [43, 61, 62] and the results of the Origins of Multicellularity project [10]. Detailed information regarding this figure, including CDK protein accession numbers, is given in Additional file 6: Table S1.
