Enhanced sampling of glutamate receptor ligand-binding domains

Research output: Contribution to journalReview articlepeer-review

Abstract

The majority of excitatory synaptic transmission in the central nervous system is mediated by ionotropic glutamate receptors (iGluRs). These membrane-bound protein assemblies consist of modular domains that can be genetically isolated and expressed, which has resulted in a plethora of crystal structures of individual domains in different conformations bound to different ligands. These structures have presented opportunities for molecular dynamics (MD) simulation studies. To examine the free energies that govern molecular behavior, simulation strategies and algorithms have been developed, collectively called enhanced sampling methods This review focuses on the use of enhanced sampling MD simulations of isolated iGluR ligand-binding domains to characterize thermodynamic properties important to receptor function.
