CC   -!- FUNCTION: Plays a role in the removal of cohesin from kinetochores on
CC       mitotic chromosomes and is required for centromere resolution.
CC       {ECO:0000269|PubMed:18202360}.
CC   -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown leads to impaired removal
CC       of the cohesin component scc-1 from kinetochores on mitotic metaphase
CC       chromosomes. {ECO:0000269|PubMed:18202360}.
CC   -!- SIMILARITY: Belongs to the type II topoisomerase family.
CC       {ECO:0000255|RuleBase:RU362094}.
CC   -!- CAUTION: Lacks the conserved ATP binding sites, the conserved active
CC       site tyrosine at position 404, the conserved isoleucine at position 455
CC       important for DNA bending, and the conserved magnesium binding site at
CC       position 143, and therefore probably lacks topoisomerase activity.
CC       {ECO:0000305}.
