ColabDock: inverting AlphaFold structure prediction model for protein-protein docking with experimental restraints

Abstract: Prediction of protein complex structures and interfaces potentially has wide applications and can benefit the study of biological mechanisms involving protein-protein interactions. However, the surface prediction accuracy of traditional docking methods and AlphaFold-Multimer is limited. Here we present ColabDock, a framework that makes use of ColabDesign, but reimplements it for the purpose of restrained complex conformation prediction. With a generation-prediction architecture and trained ranking model, Colab… Show more

“…We compare tFold-Ag with currently available end-to-end methods, including AlphaFold-Multimer [5], Uni-Fold MuSSe [23], and RoseTTAFold2 [28], as well as docking-based methods such as conventional docking methods like ZDock [9], Clus-Pro [8], HDock [10], and deep-neural-network-involved docking methods such as EquiDock [11], dyMEAN [12], and ColabDock [13]. tFold-Ag and other end-to-end methods (sequences-to-complex structure) can directly predict the complex structure using input sequences, whereas docking-based methods (structures-to-complex structure) necessitate the structures of individual components to predict the final structure of the complex.…”

“…Other works [7,61] have applied these restraints to sift through and select the most plausible structures from a pool of candidates. More recently, with the advent of AlphaFold, researchers [13] have been exploring how to combine these restraints with pre-trained models to enhance prediction accuracy.…”

“…We docked the full VP3 structure of our capsid onto the ALPL receptor structure with the constraints that the interaction pairs of residues identified using our AlphaFold-multimer predicted structure. The docking procedure was performed using local implementation ColabDock 56 .…”

“…On the other hand, the recent development of predictors relying on large language models (LLM) opens new perspectives in that field. , In particular, the lower quality of the ESMFold predictions might be compensated by the considerable decrease of the calculation time required by language models. Finally, ColabDock has been proposed to perform a form of docking restrained by experimental data . Several studies have addressed the ability of AF2 to predict protein–peptide complexes .…”
