This domain is found at the C-terminal end of Cohesin subunit SCC3 from Saccharomyces cerevisiae and similar proteins from yeasts. SCC3 is a component of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. This domain is is composed of a continuously twisted tandem array of antiparallel alpha-helices resembling tandem HEAT repeats. It binds to two small sections within Scc1, the other component of the complex [1,2].	Domain
