Plays a central role in chromosome cohesion during meiosis and mitosis by preventing premature dissociation of cohesin complex from centromeres after prophase, when most of cohesin complex dissociates from chromosomes arms. May act by protecting or Rad21 from cleavage by Sse/separase. Required during meiosis in both males and females.4 Publications

Phosphorylation by polo-like kinase (PLK) on Thr-331 antagonizes cohesive function. Phosphorylation on Thr-331 at the metaphase anaphase transition leads to its dissociation from centromeres. In contrast, phosphorylation by aurB/ial on either Ser-124, Ser-125 or Ser-126 is required for association with centromeres.2 Publications
