SEQUENCE SIMILARITIES

Belongs to the rad21 family.

TISSUE SPECIFICITY

Expressed in the gut (at protein level).

DEVELOPMENTAL STAGE

Regulated in a cell cycle-dependent manner: expression increases in late S phase and reaches maximum in G2 at the nucleotide level. Not regulated during the cell cycle (at protein level).

POST-TRANSLATIONAL MODIFICATION

Cleaved by separase/ESPL1 at the onset of anaphase; this cleavage is required for sister chromatid separation and cytokinesis. Cleaved by caspase-3/CASP3 or caspase-7/CASP7 at the beginning of apoptosis.; Phosphorylated; becomes hyperphosphorylated in M phase of cell cycle. The large dissociation of cohesin from chromosome arms during prophase may be partly due to its phosphorylation by PLK1.

SUBCELLULAR LOCATION

Centromere, Chromosome, Nucleus, Cytoplasm, Cytoskeleton.

FUNCTION

Cleavable component of the cohesin complex, involved in chromosome cohesion during cell cycle, in DNA repair, and in apoptosis. 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 separase/ESPL1 and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis. Also plays a role in apoptosis, via its cleavage by caspase-3/CASP3 or caspase-7/CASP7 during early steps of apoptosis: the C-terminal 64 kDa cleavage product may act as a nuclear signal to initiate cytoplasmic events involved in the apoptotic pathway.
