Plays an important role in excitation-contraction coupling. Publication Abstract from PubMed Gabapentinoid drugs for pain and anxiety act on the Ca(V)alpha(2)delta-1 and Ca(V)alpha(2)delta-2 subunits of high-voltage-activated calcium channels (Ca(V)1s and Ca(V)2s). Here we present the cryo-EM structure of the gabapentin-bound brain and cardiac Ca(V)1.2/Ca(V)beta(3)/Ca(V)alpha(2)delta-1 channel. The data reveal a binding pocket in the Ca(V)alpha(2)delta-1 dCache1 domain that completely encapsulates gabapentin and define Ca(V)alpha(2)delta isoform sequence variations that explain the gabapentin binding selectivity of Ca(V)alpha(2)delta-1 and Ca(V)alpha(2)delta-2.
