Sequence alignment of ligand binding sites of human androgen receptor (AR) and progesterone receptor (PR).

<p>The amino acids showing sequence identity in both the receptors are shown as white text with blue background, whereas, the rest of the amino acids are shown in black text. The initial and final position of each receptor in the alignment is also provided. The position-equivalent-residues (residues of both receptors falling at similar column position in the alignment) overlapping among the interacting residues of methylbishydroxyphenylpentene (MBP), are marked by red triangles.
