Structural insight into the constitutive repression function of the nuclear receptor Rev-erbbeta.

The Rev-erb family is an orphan nuclear receptor acting as a negative regulator of transcription. Rev-erbalpha and Rev-erbbeta are crucial components of the circadian clock and involved in various lipid homeostasis. They are unique nuclear receptors that lack the activation function 2 helix (AF2-helix) required for ligand-dependent activation by other members of nuclear receptors. Here, we report the crystal structure of Rev-erbbeta (NR1D2) in a dimeric arrangement. The putative ligand-binding pocket (LBP) of Rev-erbbeta is filled with bulky hydrophobic residues resulting in a residual cavity size that is too small to allow binding of any known ligand molecules. However, an alternative conformation of the putative LBP observed in another crystal form suggests the flexibility of this region. The kinked conformation of helix H11 allows helix H11 to bend toward helix H3 over the putative ligand binding pocket by filling and closing the cavity with its side-chains. In the absence of the AF2-helix and a cognate ligand, Rev-erbbeta appears to stabilize the hydrophobic cluster in the putative ligand binding pocket and provide a structural platform for co-repressor binding by adopting the unique geometry of helix H11, a suitable conformation for the constitutive repression activity.

Figure 1.
Figure 1. Overall structure of human Rev-erbβ LBD. (a) Schematic overview of the Rev-erbβ dimer with the 2-fold axis in a vertical orientation (left) and in a horizontal orientation, perpendicular to the plane (right). Each monomer is colored blue and green with the helix H11 colored red. (b) Stereo view of the superposition of the C^α traces of the Rev-erbβ (blue) monomer and the RARγ (red) monomer. A region of the amino aacid residues 182–218 of RARγ is omitted from the Figure for clarity. (c) Superposition of the structure of Rev-erbβ LBD (blue) onto the RARγ LBD (cyan), represented in solid rendering (α helices in cylinders and β strands in arrows). The different regions between the two LBDs correspond to the tilt of the N termini of H3 and H7 toward the center of the LBP and the lid-like conformation of H11 (pink). The ligand, all-trans retinoic acid, bound to RARγ is shown using orange spheres.

Figure 4. Model structures of NCoR1 peptides, ID-I and ID-II, bound to Rev-erbβ. (a) Residues comprising the surface groove of Rev-erbβ and those involved in binding to the NCOR1 peptide ID-I are drawn using green sticks. Co-repressor peptide ID-I is colored orange with some side-chains drawn as sticks except for F575 Residues F409, L572, F405 and F575 buried in the hydrophobic cluster are shown in blue. (b) Co-repressor peptide ID-II, interacting to the same groove as ID-I, is colored orange with some side-chains drawn as sticks. The surface groove is shown with residues (green) that affected the binding to NCoR1 in previous mutational studies. Some residues lining the groove are labeled. Helix H11 is highlighted in red.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
