Identification and characterization of HAP4: a third component of the CCAAT-bound HAP2/HAP3 heteromer.
Open accessAbstract
The CYC1 gene of Saccharomyces cerevisiae is positively regulated by the HAP2 and HAP3 proteins, which form a heteromeric complex that binds to a CCAAT box in the upstream activation site, UAS2, and which activate transcription in a nonfermentable carbon source. We carried out a genetic analysis to identify additional trans-acting regulatory factors exerting their effects through UAS2. We present the identification and characterization of a new locus, HAP4, which is shown to encode a subunit of the DNA-binding complex at UAS2. In the hap4 mutant, the binding of HAP2 and HAP3 (HAP2/3) is not observed in vitro. The HAP4 gene is regulated transcriptionally by a carbon source, suggesting that it encodes a regulatory subunit of the bound complex. The sequence of HAP4 shows a highly acidic region, which innactivated the protein when deleted. Replacement of this region with the activation domain of GAL4 restored activity, suggesting that it provides the principal activation domain to the bound HAP2/3/4 complex.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
