    ..Although Swd2 is normally required for bringing APT to genes, deletion of SET1 restores both viability and APT recruitment to a strain lacking Swd2. We propose a model in which Swd2 is required for APT to overcome antagonism by COMPASS. ..

    ..Based on these results and the exclusive conservation of the protein in the fungal kingdom, we hypothesize that Yrb30p represents a novel modulator of the Ran GTPase switch related to fungal lifestyle. ..
