    What's a GeneRIF?
    1. We propose that the Rim15-Endosulfine( Igo1 and Igo2 )-PP2ACdc55 signalling module triggers entry into quiescence and gametogenesis by regulating dephosphorylation of distinct substrates

    2. Igo1/Igo2 can inhibit Cdc55 in early mitosis, but their contribution to Cdc55 regulation is relatively minor compared with the role of Zds1/Zds2.

    3. We conclude that Greatwall, endosulfines((Igo1 and Igo2), and PP2A are part of a regulatory module that has been conserved during evolution irrespective of PP2A function in the control of mitosis

    • Protein required for initiation of the G0 program; prevents degradation of nutrient-regulated mRNAs via the 5'-3' mRNA decay pathway; phosphorylation (S63) by Rim15p increases interaction with and inhibition of PP2A-Cdc55 for timely mitotic progression; can also activate PP2A-Cdc55 complexes and influence Cdc55p localization along with Igo2p; GFP protein localizes to the cytoplasm and nucleus; IGO1 has a paralog, IGO2, that arose from the whole genome duplication
