Analysis of Scc1-deficient cells defines a key metaphase role of vertebrate cohesin in linking sister kinetochores.

Abstract

Cleavage of the cohesin subunit Scc1p/Mcd1p/Rad21 permits sister chromatid separation and is considered to trigger anaphase onset. It has also been suggested that the cohesin complex is essential for chromosome condensation and for assembling fully functional kinetochores. Here, we used vertebrate cells conditionally deficient in Scc1 to probe cohesin… (More)
