Status

Functioni

Regulator of sister chromatid cohesion in mitosis stabilizing cohesin complex association with chromatin. May antagonize the action of WAPL which stimulates cohesin dissociation from chromatin. Cohesion ensures that chromosome partitioning is accurate in both meiotic and mitotic cells and plays an important role in DNA repair. Required for efficient DNA double-stranded break repair.3 Publications

Miscellaneous

Named sororin after the Latin word 'soror', which means 'sister', because of its critical role in sister chromatid cohesion.

Interactioni

Subunit structurei

Interacts with the APC/C complex (By similarity). Interacts with the chromatin-bound cohesin complex; the interaction is indirect, occurs after DNA replication and requires acetylation of the cohesin component SMC3. Interacts (via the FGF motif) with PDS5A and PDS5B; the interaction is direct and prevents the interaction of PDS5A with WAPL.By similarity3 Publications
