Maradeo ME and Skibbens RV (2010) Epitope tag-induced synthetic lethality between cohesin subunits and Ctf7/Eco1 acetyltransferase. FEBS Lett 584(18):4037-40
Abstract: Ctf7/Eco1-dependent acetylation of Smc3 is essential for sister chromatid cohesion. Here, we use epitope tag-induced lethality in cells diminished for Ctf7/Eco1 activity to map cohesin architecture in vivo. Tagging either Smc1 or Mcd1/Scc1, but not Scc3/Irr1, appears to abolish access to Smc3 in ctf7/eco1 mutant cells, suggesting that Smc1 and Smc3 head domains are in direct contact with each other and also with Mcd1/Scc1. Thus, cohesin complexes may be much more compact than commonly portrayed. We further demonstrate that mutation in ELG1 or RFC5 anti-establishment genes suppress tag-induced lethality, consistent with the notion that the replication fork regulates Ctf7/Eco1.CI - Copyright (c) 2010 Federation of European Biochemical Societies.
