1 Inhibition of Kv4.3/KChIP2.2 channels by bupivacaine and its modulation by the pore mutation Kv4.3V401I. Bupivacaine potassium voltage-gated channel subfamily D member 3 Homo sapiens
2 This study elucidates the molecular mechanisms of bupivacaine interaction with complexes formed by Kv4.3 and KChIP2.2 as well as the modulatory effect of KChIP2.2. Bupivacaine potassium voltage-gated channel subfamily D member 3 Homo sapiens
3 RESULTS: Inhibition of Kv4.3wt/KChIP2.2 channels by bupivacaine was concentration-dependent and reversible. Bupivacaine potassium voltage-gated channel subfamily D member 3 Homo sapiens
4 KChIP2.2 altered the response of Kv4.3wt channels to bupivacaine and bupivacaine modulated KChIP2.2 effects on Kv4.3wt channels. Bupivacaine potassium voltage-gated channel subfamily D member 3 Homo sapiens
5 CONCLUSIONS: These results indicate that bupivacaine blocks Kv4.3/KChIP2.2 channels from the open state. Bupivacaine potassium voltage-gated channel subfamily D member 3 Homo sapiens
