Cohesin. Cohesin, binds sister chromatids together during metaphase (PDB: 1w1w).

Genetic data
Gene code: [1] ID#: GI:2570096
Protein Structure/Function
Structure: [2]1W1W

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.
