Structure of the glucocorticoid receptor (NR3C1) gene 5′ untranslated region: identification, and tissue distribution of multiple new human exon 1

Turner, Jonathan D, Muller, Claude P·2005·Journal of Molecular Endocrinology

Abstract

The 5' untranslated region (UTR) of the glucocorticoid receptor (GR) plays a key role in determining tissue-specific expression and protein isoforms. Analysis of the 5' UTR of the human GR (hGR) has revealed 11 splice variants of the hGR exon 1, based on seven exon 1s, four of which (1-D to 1-F and 1-H) were previously unknown. All of the exon 1 variants have unique splice donor sites and share a common exon 2 splice acceptor site. Due to an upstream in-frame TGA stop codon the predicted translation from all splice variants is identical. The four new exon 1s show remarkable similarity with their rat homologues. Exon 1-D starts and finishes 17 and 36 bp upstream of the corresponding ends of the rat exon 1(4). Exon 1-E is only 6 bp longer than its homologue exon 1(5). Exon 1-F contains two short inserts of 11 and 6 bp when compared with the rat 1(7). 1-H is 18 bp longer than the corresponding rat 1(11). In addition to these new exons, we found that the human exon 1-C occurs as three distinct splice variants, covering the region homologous to the rat exons 1(9) and 1(10). All of the alternative hGR exons 1s presented here were found to be transcribed in human tissue. The human hippocampus expresses mRNA of all the exon 1 variants, while the expression of the other exon 1s seems to be tissue specific. While exon 1-D is only in the hippocampus, exons 1-E and 1-F are also detected in the immune system, and exon 1-H additionally in the liver, lung and smooth muscle. The 5' region of…

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.
