CACNA1G encodes the alpha-1G subunit of low-voltage-activated T-type calcium channels (Cav3.1).
- 24 transmembrane segments
- Four homologous domains (I-IV)
- Unique gating properties compared to high-voltage-activated channels
- Low-threshold calcium influx
- Neuronal pacemaking and rhythmic firing
- Thalamic oscillation states (sleep/wake cycles)
- Dendritic integration
- T-type calcium spike bursts
- Alzheimer's: Altered T-type channel function affects neuronal excitability
- Parkinson's: Dysregulated thalamic oscillations
- Epilepsy: Gain-of-function mutations cause childhood absence epilepsy
- Neuropathic Pain: Upregulated in sensory neurons
- T-type calcium channel blockers (ethosuximide, valproic acid)
- Zonisamide
- New selective inhibitors in development
