Conservation profile of the residues implicated in identified salt bridges in sequence alignments from heterodimeric nuclear receptors sequences.

<p>The alignment is represented using the WebLogo 3 program <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003012#pcbi.1003012-Crooks1" target="_blank">[70]</a> with the degree of sequence conservation being represented by the height of the amino-acid letter, i.e. the more conserved is the amino acid, the greater is the relative height. Heterodimeric sequences are extracted from the alignment performed by Brelivet et al <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003012#pcbi.1003012-Brelivet1" target="_blank">[29]</a>.
