Abstract

Uncertainty as to which member of a family of DNA-binding transcription factors regulates a specific promoter in intact cells is a problem common to many investigators. Determining target gene specificity requires both an analysis of protein binding to the endogenous promoter as well as a characterization of the functional consequences of transcription factor binding. By using a formaldehyde crosslinking procedure and Gal4 fusion proteins, we have analyzed the timing and functional consequences of binding of Myc and upstream stimulatory factor (USF)1 to endogenous cellular genes. We demonstrate that the endogenous cad promoter can be immunoprecipitated with antibodies against Myc and USF1. We further demonstrate that although both Myc and USF1 can bind to cad, the cad promoter can respond only to the Myc transactivation domain. We also show that the amount of Myc bound to the cad promoter fluctuates in a growth-dependent manner. Thus, our data analyzing both DNA binding and promoter activity in intact cells suggest that cad is a Myc target gene. In addition, we show that Myc binding can occur at many sites in vivo but that the position of the binding site determines the functional consequences of this binding. Our data indicate that a post-DNA-binding mechanism determines Myc target gene specificity. Importantly, we have demonstrated the feasibility of analyzing the binding of site-specific transcription factors in vivo to single copy mammalian genes.

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.
