The study of higher order chromosome structure and how it is modified through the course of the cell cycle has fascinated geneticists, biochemists, and cell biologists for decades. The results from many diverse technical avenues have converged in the discovery of a large superfamily of chromosome-associated proteins known as SMCs, for structural maintenance(More)
'Cohesin' is a highly conserved multiprotein complex thought to be the primary effector of sister-chromatid cohesion in all eukaryotes. Cohesin complexes in budding yeast hold sister chromatids together from S phase until anaphase, but in metazoans, cohesin proteins dissociate from chromosomes and redistribute into the whole cell volume during prophase,(More)
