Transcription factor that behaves as a negative regulator of adhesion. Recognizes specifically the canonical CSL response element GTGA/GGAA. May also play a cbf12-antagonistic role in the regulation of a number of other important processes such as extracellular material production, colony morphogenesis, ploidy maintenance, or meiosis. Expression is fairly constant throughout the growth phases of haploid cells and similar mRNA levels were found in vegetative diploid cells. Leads to cold sensitivity, slow growth, and altered colony morphology. Belongs to the Su(H) family.
