Abstract: | "The product of the BAR1 gene of Saccharomyces cerevisiae is synthesized only in the a cell type and inactivates alpha-factor, the mating pheromone made by alpha cells. The MAT alpha 2 protein represses the transcription of a-cell-specific genes, including BAR1, in alpha and a/alpha diploid cells. Transcription of BAR1 in a cells in stimulated upon exposure to alpha-factor. Deletion analysis of the 5' noncoding region of the BAR1 gene revealed that the major upstream activation site (UAS) overlaps the 31 bp operator sequence required for MAT alpha 2 repression. This result has implications for the negative control of transcription in yeast. The deletion analysis also indicated that the sequence TGAAACA mediates alpha-factor stimulation" |
