Physical and functional interactions between the transcription factor PU.1 and the coactivator CBP

Abstract

Yeast two-hybrid system was employed to isolate novel proteins that physically interact with PU.1, a member of Ets family transcription factors. Sequence analyses of several isolated clones positive for beta-galactosidase activity revealed that one of these clones was confirmed to encode a transcriptional coactivator, CREB binding protein (CBP). GST binding assay showed that the interacting sites were located at the transcriptional activation domain of PU.1 through 74-122 and the region spanning residues 1283-1915 of CBP. CBP potentiated PU.1-mediated transcription of the reporter gene driven by the multimerized PU.1-binding sites, suggesting that CBP functions as a coactivator for PU.1. Considering that CBP is a limited cellular component to function as a coactivator for several transcription factors, CBP may mediate synergistic and antagonistic interactions between PU.1 and other transcription factors during the process of hematopoietic cell differentiation.

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.
