Cohesin subunit rad21

UniProtKB accession:  P30776

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Cleavable component of the cohesin complex, involved in chromosome cohesion during cell cycle. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At metaphase-anaphase transition, this protein is cleaved by cut1 and dissociates from chromatin, allowing sister chromatids to segregate. Also involved in the DNA double-strand-break (DSB) repair system.
