Transcription factor which function may be to trigger the increase of adhesion at stationary phase, possibly by counteracting or replacing cbf11 at the respective promoters. May also play a cbf11-antagonistic role in the regulation of a number of other important processes such as extracellular material production, colony morphogenesis, ploidy maintenance, or meiosis. Expression increases as the cells enter the stationary phase, with a statistically significant peak at the late stationary phase. A similar increase in the mRNA levels is found in the sporulating cells. Belongs to the Su(H) family.
