Disease

SMC3_HUMAN Cornelia de Lange syndrome. The disease is caused by mutations affecting the gene represented in this entry.

Function

SMC3_HUMAN Central component of cohesin, a complex required for chromosome cohesion during the cell cycle. The cohesin complex may form a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. Cohesion is coupled to DNA replication and is involved in DNA repair. The cohesin complex plays also an important role in spindle pole assembly during mitosis and in chromosomes movement.^{[1] [2]}
