* Information From OMIM

Description: Eukaryotic sister chromatids remain connected from the time of synthesis until they are separated in anaphase. This cohesion depends on a complex of proteins known as cohesins. In vertebrates, unlike in yeast, the cohesins dissociate from chromosome arms earlier in M phase, during prophase. Small amounts of cohesin remain near the centromere until metaphase, with complete removal at the beginning of anaphase. Cohesin complexes contain SCC1 (RAD21), SMC1 (OMIM:300040), SMC3 (CSPG6; OMIM:606062), and either SA1 (STAG1; OMIM:604358) or SA2 (STAG2; OMIM:300826). The complexes, in turn, interact with PDS5 (see OMIM:613200), a protein implicated in chromosome cohesion, condensation, and recombination in yeast (summary by Sumara et al., 2000).
