Amino acid similarity of Cak1At to other CAK proteins. (A) Predicted amino acid sequence of Cak1At and alignment with CAK proteins from other organisms. Identical amino acids are indicated by asterisks. Dashes represent gaps introduced to give maximal identity. The threonine residue indicated by + represents the phosphoregulatory site of CAK. (B) Phylogenetic tree obtained by amino acid sequence comparison of human Cdk2 (Cdk2.Hs), Cdk4 (Cdk4.Hs), Cdk7 (Cdk7.Hs), Xenopus MO15 (MO15.Xl), rice R2 (R2.Os), S. cerevisiae Cdc28 (Cdc28.Sc), Cak1 (Cak1.Sc), Kin28 (Kin28.Sc), Sch. pombe Cdc2 (Cdc2.Sp), Crk1 (Crk1.Sp), and Arabidopsis Cdc2aAt and Cdc2bAt.
