ジャーナル: Nat Struct Mol Biol / 年: 2023 タイトル: Structural basis for Caαδ:gabapentin binding. 著者: Zhou Chen / Abhisek Mondal / Daniel L Minor / 要旨: 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.
