TriGlue: Generative Model for Molecular Glue-Induced Ternary Complexes
A novel computational framework named TriGlue has been introduced for the creation of molecular glue degraders, facilitating the formation of ternary complexes between a target protein and an E3 ubiquitin ligase. This research, detailed in arXiv (2607.22143), explores the relatively uncharted territory of computational design for molecular glues. In contrast to traditional structure-based drug design, this method deals with unknown protein-protein interfaces and necessitates the concurrent modeling of ligand generation, docking, and ternary complex formation. TriGlue addresses this by breaking it down into two phases: estimating the interface and generating the complex conditioned on that interface. The initial phase employs an SE(3)-equivariant module for interface prediction, drawing inspiration from biological mechanisms of molecular glue activity, potentially enhancing targeted protein degradation therapies.
