Atomistic Mechanisms of Calcium Permeation Modulated by Q/R Editing and Selectivity Filter Mutations in GluA2 AMPA Receptors

Florian Heiser, Johann Biedermann, Ece Kuru…·Han Sun

This study investigates the atomistic mechanisms of calcium permeation in GluA2 AMPA receptors, showing how Q/R editing and selectivity filter mutations modulate ion selectivity and conductance.
