Plays a central role in chromosome cohesion during meiosis by preventing premature dissociation of cohesin complex from centromeres after prophase; when most of cohesin complex dissociates from chromosomes arms. May act by protecting centromeric rec8 from separase degradation during anaphase I. {ECO:0000269|PubMed:14730319; ECO:0000269|PubMed:14972679; ECO:0000269|PubMed:16303567}.
