Abstract
The expression of the PHO5 gene of Saccharomyces cerevisiae is transcriptionally regulated in response to the level of inorganic phosphate present in the growth medium. We have identified, by DNA deletion analysis, the sequences (upstream activator sequences) that mediate this response. The sequence 5' CTGCACAAATG 3' is present in two copies located within a 60-base-pair region. The presence of a single copy of the sequence is sufficient for the phosphate-mediated transcriptional response. In addition, a DNA fragment that contains two copies of this sequence will act to repress transcription of a CYC1-lacZ fusion when placed either upstream or downstream of the CYC1 activator sequence.Entities:
