Cohesion proteins

Webcient for cohesion, because several proteins have been identified that are essential for cohesion that do not ap-pear to regulate catenations between sister chromatids. For yeast minichromosomes, it has furthermore been shown recently that these proteins can mediate cohesion in the absence of catenation (Ivanov and Nasmyth 2007).
