Cav1.2 (encoded by CACNA1C) is the primary L-type voltage-gated calcium channel in neurons and cardiac myocytes. It couples electrical activity to biochemical signaling and plays essential roles in synaptic plasticity, gene transcription, and cellular excitability.
Cav1.2 has the characteristic structure of high voltage-activated calcium channels:
Cav1.2 mediates L-type calcium currents with distinct properties:
| Drug/Agent | Mechanism | Status |
|---|---|---|
| Nimodipine | Dihydropyridine antagonist | Approved (CNS penetrant) |
| Amlodipine | Dihydropyridine antagonist | Approved (hypertension) |
| Diltiazem | Benzothiazepine antagonist | Approved |
| Verapamil | Phenylalkylamine antagonist | Approved |
| Bay K8644 | Agonist | Research use |
The study of Cav1.2 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
