Molecular dynamics simulations of immune receptor and ligand proteins in their native membrane environment allow to determine the orientational and structural variability of the proteins and protein complexes. The simulations complement the static, "membrane-free" structural information obtained from cryo-EM structures of transmembrane proteins in detergent micelles or from crystal structures of extracellular protein domains. Here we describe how to set up and perform simulations of transmembrane receptors, ligands, and receptor-ligand complexes.
