Notes:
The PHO80 gene, which is one of the regulatory genes exerting negative control in the pho system of Saccharomyces cerevisiae, was cloned. The 1·8 kb DNA fragment carrying the PHO80 gene was sequenced and one open reading frame large enough to encode 293 amino acids was found in the sequence. Northern blot analysis of poly(A)+-RNA isolated from cells grown under repressed and derepressed conditions revealed that (i) the size of the PHO80 message was around 1·4 kb, (ii) the expression of the PHO80 gene was not affected by the presence or absence or absence of inorganic phosphate in the medium, and (iii) the expression of the PHO80 gene was not affected by pho2, pho4, pho81, or by pho80 itself. a centromere sequence was found downstream of the PHO80 coding region.
