Cohesin is the protein responsible for binding the sister chromatids during mitosis after S phase. At metaphase, most cohesin is removed,except for some at the centromere. At Anaphase, securin,an inhibitory subunit of separase, is hydrolyzed. Separase hydrolyzes the remaining cohesin.de:Cohesin ja:コヒーシン
