The familial hemiplegic migraine type 1 mutation K1336E affects direct G protein-mediated regulation of neuronal P/Q-type Ca 2+ channels

Abstract excerpt

BACKGROUND: Familial hemiplegic migraine type 1 (FHM-1) is an autosomal dominant form of migraine with aura characterized by recurrent migraine, hemiparesis and ataxia. FHM-1 has been linked to missense mutations in the CACNA1A gene encoding the pore-forming subunit of the neuronal voltage-gated P/Q-type Ca(2+) channel (CaV2.1α1). METHODS: Here, we explored the effects of the FHM-1 K1336E mutation on G...
