Figure 2. Analysis of the binding and kinase-activating properties of different Cyclin A2 alleles in NIH3T3 cells.
WT, D171A, Triple (M200A, L204A and W207A), M200A, L204A, W207A (A), and WT, E180A, E210Q, Double (W207L, E210Q), K256A, L282R and E285A Cyclin A2 alleles (B). Immunoprecipitation using anti-Flag-agarose affinity gel was performed on NIH3T3 cells extracts after transfection of plasmids encoding the above-mentioned mutants. Immune complexes were either submitted to Western blotting to identify binding partners or analyzed for their histone H1-kinase activity. Schematic representation of the importance of the different Cyclin A2 domains for partners association and kinase-induced activity. The bars represent (high-medium-low according to their size) the importance of the indicated region of Cyclin A2 for its association with partners or kinase inducing activity (C).
