Structure: | [2]1W1W |
Cohesin is the protein responsible for binding the sister chromatids during mitosis through the G2 phase and into mitosis 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.
