PubMed Abstract: Gabapentinoid drugs for pain and anxiety act on the Caαδ-1 and Caαδ-2 subunits of high-voltage-activated calcium channels (Ca1s and Ca2s). Here we present the cryo-EM structure of the gabapentin-bound brain and cardiac Ca1.2/Caβ/Caαδ-1 channel. The data reveal a binding pocket in the Caαδ-1 dCache1 domain that completely encapsulates gabapentin and define Caαδ isoform sequence variations that explain the gabapentin binding selectivity of Caαδ-1 and Caαδ-2.
