| pubmed-article:11137006 | pubmed:abstractText | Sister chromatid cohesion depends on a complex called cohesin, which contains at least four subunits: Smc1, Smc3, Scc1 and Scc3. Cohesion is established during DNA replication, is partially dismantled in many, but not all, organisms during prophase, and is finally destroyed at the metaphase-to-anaphase transition. A quite separate protein called Spo76 is required for sister chromatid cohesion during meiosis in the ascomycete Sordaria. Spo76-like proteins are highly conserved amongst eukaryotes and a homologue in Aspergillus nidulans, called BimD, is required for the completion of mitosis. The isolation of the cohesin subunit Smc3 as a suppressor of BimD mutations suggests that Spo76/BimD might function in the same process as cohesin. | lld:pubmed |
