Cross-Talk between PPARs and the Partners of RXR: A Molecular Perspective
Figure 3
Amino acid sequences of the I-box region of RXR, USP, COUP, RAR, TR, PPAR, and VDR. The I-box lies within Helix 9 (H9) and helix 10 (H10) (shaded) and has been shown to be essential to dimerization. The amino acid residues equivalent to hRXR E390 and K417 are also marked.
