Uncovering novel cell cycle players through the inactivation of securin in budding yeast.

Sarin S., Ross K.E., Boucher L., Green Y., Tyers M., Cohen-Fix O.

Budding yeast securin/Pds1p, an inhibitor of the anaphase activator separase/Esp1p, is involved in several checkpoint pathways and in promoting Esp1p's nuclear localization. Using a modified synthetic genetic array (SGA) screen for genes that become essential in the absence of Pds1p, we uncovered roles for uncharacterized genes in cell cycle processes, including Esp1p activation.
