The complex of the rat glucocorticoid receptor (GR) DNA binding domain (DBD) and half-site sequence of the consensus glucocorticoid response element (GRE) has been studied by two-dimensional 1H NMR spectroscopy. The DNA fragment is a 10 base-pair oligonucleotide, 5'd(GCTGTTCTGC)3'.5'd-(GCAGAACAGC)3', containing the stronger binding GRE half-site hexamer, with GC base pairs at each end. The 93-residue GR-DBD contains an 86-residue segment corresponding to residues 440-525 of the rat GR. Eleven NOE cross peaks between the protein and DNA have been identified, and changes in the chemical shift of the DNA protons upon complex formation have been analyzed. Using these protein-DNA contact points, it can be concluded that (i) the "recognition helix" formed by residues C460-E469 lies in the major groove of the DNA; (ii) the GR-DBD is oriented on the GRE half-site such that residues A477-D481, forming the so-called D-loop, are available for protein-protein interaction in the GR-DBD dimer on the intact consensus GRE; and (iii) the 5-methyl of the second thymine in the half-site and valine 462 interact, confirming indirect evidence [Truss et al. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 7180-7184; Mader et al. (1989) Nature 338, 271-274] that both play an important role in GR-DBD DNA binding. These findings are consistent with the model proposed by Härd et al. [(1990) Science 249, 157-160] and the X-ray crystallographic complex structure determined by Luisi et al. [(1991) Nature 352, 497-505].

D011965 Receptors, Glucocorticoid Cytoplasmic proteins that specifically bind glucocorticoids and mediate their cellular effects. The glucocorticoid receptor-glucocorticoid complex acts in the nucleus to induce transcription of DNA. Glucocorticoids were named for their actions on blood glucose concentration, but they have equally important effects on protein and fat metabolism. Cortisol is the most important example.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
