Function

  • L-type Ca+2 channels (long-lasting) belong to the 'high-voltage activated' (HVA) group
  • blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, & by omega-agatoxin-IIIA (omega-Aga-IIIA)
  • insensitive to omega-conotoxin-GVIA (omega-CTx-GVIA) & omega-agatoxin-IVA (omega-Aga-IVA)
