UniProtKB description:  Regulatory protein, which plays a central role in chromosome stability. Probably acts by blocking the action of key proteins. During the mitosis, it blocks Separase/ESP1 function, preventing the proteolysis of the cohesin complex and the subsequent segregation of the chromosomes. At the onset of anaphase, it is ubiquitinated, conducting to its destruction and to the liberation of ESP1.
