(A to D) Analytical SEC experiments were performed to demonstrate the interactions between different CENP-C variants and CENP-ANCPs. Red lines between 1.4 and 1.6 ml of elution volume indicate fractions collected for SDS-PAGE analysis shown in (E). The SEC chromatograms and SDS-PAGEs of all individual components are shown in fig. S5. (E) SDS-PAGE result showing the pooled fractions of the peak 1 complexes shown in the SEC chromatograms in (A) to (D). (F) Sedimentation coefficient distributions obtained from the sedimentation velocity AUC experiments using CENP-ANCP (left), CENP-ANCP + MBPCENP-CF-WT (middle), and CENP-ANCP + MBPCENP-CF-Δmotif2 (right). The table summarizes the results of the three experiments.
