Figure 3: Conserved interactions in the ACTR -CBP complex. a, Sequence alignment of the CBP binding domain of human ACTR(1018 -1088) and a representative set of p160 coactivators. b, Sequence alignment of the ACTR binding domain of murine CBP with other members of the CBP/p300 family. Conserved hydrophobic residues (green), conserved acidic residues (red), conserved basic residues (blue), and other conserved residues (orange) are indicated (h, human; m, murine, x, Xenopus laevis; d, Drosophila; dr, Danio rerio; c, Caenorhabditis elegans). c, -X-X- - and - -X-X- hydrophobic contact map defining the interface between ACTR and CBP ( denotes hydrophobic residue). The four -X-X- - motifs that comprise the hydrophobic core are enclosed by a green box. The buried intermolecular salt bridge is indicated. d, Close-up of the salt bridge between Arg 2105 and Asp 1068 salt bridge. The solvent-accessible surface of ACTR is shown.
