Abstract

Recently, we have shown that receptors for vitamin D3 (VDR), thyroid hormone (TR), and retinoic acid (RAR) activate preferentially through direct repeats (DRs) spaced by 3, 4, and 5 nucleotides, respectively. In addition, the RAR can activate weakly through DRs spaced by 2 nucleotides. A common feature of RAR, TR, and VDR is their ability to heterodimerize with the retinoid X receptor (RXR) through their ligand-binding domains (LBDs) to form high-affinity DNA-binding complexes that are specific for appropriately spaced repeats. In this paper we demonstrate that selective binding of RAR-RXR and TR-RXR heterodimers to their cognate DRs is a consequence of a novel cooperative dimer interaction within the DNA-binding domains (DBDs). Accordingly, a region in the first zinc finger of the TR and RAR DBDs interacts with the second zinc finger in the RXR DBD to promote selective DNA-binding to DRs spaced by 4 and 5 nucleotides, respectively. The resulting polarity established by this interaction places RXR in the 5' position of the direct repeats. These data provide a mechanism for selective receptor recognition of a restricted set of target sequences in DR DNA and explains the structural basis for physiological specificity.

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.
