Tertiary structures were predicted using the TASSER set of programs and assembled into groups of potential homologues. Models were rendered using PyMol. Figures 1A through 1I correspond to Homo sapiens FKBP1, FKBP2, FKBP3, FKBP4/5, FKBP6, FKBP7, FKBP8, FKBP9/10 and FKBP11/14, respectively. FKBPs from other organisms were placed into groups of orthologues based on structural similarity to one or more of the Homo sapiens FKBPs.
