Figure 2.

(A) Schematic representation of full length BBX21 and BBX24 proteins. B1 and B2 represent the first and second B-box. Motif 7 and Motif 6 are denoted by M6 and M7. The black arrowhead indicates the position from where the C-terminal regions were swapped to make BB21C24 and BB24C21. The green arrowhead indicates the position from where the regions containing M6 motif were swapped. (B) Multiple sequence alignment of M7 and M6 motifs in the C-terminal regions of BBX20-BBX25 using Clustal Omega.
