Function

[RARB_HUMAN] Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence or presence of hormone ligand, acts mainly as an activator of gene expression due to weak binding to corepressors. In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function.^[1]

Publication Abstract from PubMed

The three-dimensional structure of the DNA-binding domain of the human retinoic acid receptor-beta (hRAR-beta) has been determined by nuclear magnetic resonance spectroscopy in conjunction with distance geometry, restrained molecular dynamics and iterative relaxation matrix calculations. A total of 1244 distance restraints were obtained from NOE intensities, of which 448 were intra-residue and 796 inter-residue restraints. In addition 23 chi and 30 phi dihedral angle restraints were obtained from J-coupling data. The two 'zinc-finger' regions of the 80-amino acid residue protein are followed by two alpha-helices that cross each other perpendicularly. There is a short stretch of b-sheet near the N-terminus. The alpha-helical core of the protein is well determined with a backbone root-mean-square deviation (r.m.s.d.) with respect to the average of 0.18 A and 0.37 A when the side chains of residues 31, 32, 36, 61, 62, 65 and 69 are included. The r.m.s.d. for the backbone of residues 5-80 is 0.76 A. For the first finger (residues 8-28), the r.m.s.d. of the backbone is 0.79 A. For the second finger (residues 44-62) the r.m.s.d. is 0.64 A. The overall structure is similar to that of the corresponding domain of the glucocorticoid receptor, although the C-terminal part of the protein is different. The second alpha-helix is two residues shorter and is followed by a well-defined region of extended backbone structure.
