Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Sister-chromatid cohesion is mediated by cohesin, a ring-shape complex made of four core subunits called Scc1, Scc3, Smc1, and Smc3 in Saccharomyces cerevisiae (Rad21, Psc3, Psm1, and Psm3 in Schizosaccharomyces pombe). How cohesin ensures cohesion is unknown, although its ring shape suggests that it may tether sister DNA strands by encircling them . Cohesion establishment is a two-step process. Cohesin ... [more]
