Relationship between cohesin, condensin and chromosomal passenger complexes (CPC). (a) Physical interaction network illustrating protein-protein interactions involving cohesin, condensin and CPC complexes. Nodes represent individual proteins and edges represent physical interactions. (b) Cohesin, condensin and CPC complex localization. Ipl1p-GFP, Smc3p-GFP and Smc4p-GFP localization was assessed with respect to the spindle pole marker, Spc29p-RFP in a wild-type strain. Fluorescent micrograph images illustrate representative single cells.
