The many faces of the Sigma-1 Receptor: Pathogenic variants reveal the structural determinants of ligand recognition and oligomeric interface organization
The Sigma-1 receptor (S1R) is a ligand-regulated membrane protein whose pathogenic variants are associated with motor-neuron and neurodegenerative disorders, yet its ligand conformational selectivity and receptor organization remain incompletely understood. We systematically characterized 35 pathogenic or likely pathog...
