title: King of the castle: competition between repressors and activators on the Mcm1 platform.
abstract: Darieva and coworkers (Darieva et al., 2010) have shown that the repressor Yox1 and the activator Fkh2-Ndd1 associate with opposite sides of the dimeric Mcm1 transcription factor but nevertheless compete for binding; the outcome determines expression of late mitotic genes in yeast.
