MODTIE: structure-based prediction of binary and higher-order protein complexes
v1.11. Released Oct 8, 2010.
Copyright 2005,2010 Fred P. Davis

 MODTIE predicts binary protein interactions and higher-order protein
 complexes from a set of protein sequences based on their similarity to
 template complexes of known structure. It can be used for genome-wide
 prediction, through interaction with the MODBASE database of comparative
 models (, or to score individual protein
 complexes. This package contains the software that implements the method.

 MODTIE v1.11 uses:
 * template structures from PIBASE v2010
 * domain definitions from SCOP v1.75

o Using MODTIE
 This package contains the software used to make predictions using MODTIE.
 Three programs are included for typical prediction purposes:

 1. - Predict interactions between protein sequences
                           using comparative models available in MODBASE

 2. - Score interactions between two
                  protein structures given a template complex structure

 3. - Score the structure of a protein complex

 The code is mostly in Perl, with some C code for more expensive computations.
 A users manual is provided describing the installation procedure and three
 typical run modes.

o Downloading MODTIE

 The software package is available at

 The four data files used by the package are available from Zenodo:

 1. modtie_data.modtie_v1.11.tgz (55 MB)
 2. pibase2010_subsets_residues.modtie_v1.11.tar (519 MB)
 3. pibase2010_bdp_residues.modtie_v1.11.tar (680 MB)
 4. pibase2010_data.modtie_v1.11.tar (425 MB)

o History
 MODTIE was developed at the University of California, San Francisco in the
 laboratory of Andrej Sali ( and continued at the
 Janelia Research Campus of the Howard Hughes Medical Institute

 * v1.11  adjusts for new residue numbering scheme in MODBASE
 * v1.1   upgrade to new PIBASE v2010 and SCOP domains v1.75
