General description
CACNA1A (calcium voltage-gated channel subunit alpha1 A) gene codes for the α1 subunit of neuronal CaV2.1 (P/Q-type) voltage-gated calcium channels. It is expressed throughout the central nervous system (CNS). CACNA1A gene is located on human chromosome 19p13.
Application
ω-Agatoxin IVA has been used in the manipulation of calcium influx. It has also been used in the study to characterize the spontaneous and evoked activity from murine ventral horn cultures on microelectrode arrays.
Biochem/physiol Actions
Mutations in the CACNA1A (calcium voltage-gated channel subunit alpha1 A) gene is responsible for episodic ataxia 2, familial hemiplegic migraine type 1 (FHM1) and spinocerebellar ataxia type 6 (SCA6).
Toxin found in the venom of the funnel web spider, Agelenopsis aptera. Potent, selective blocker of mammalian P-type voltage-dependent calcium channels.

Voltage-dependent calcium channels mediate calcium entry into neurons, which is crucial for many processes in the brain including synaptic transmission, dendritic spiking, gene expression and cell death. Many types of calcium channels exist in mammalian brains, but high-affinity blockers are

The peptide toxin omega-Aga-IVA blocked P-type Ca2+ channel current in rat Purkinje neurons (KD approximately 2 nM) but had no effect on identified T-type, L-type, or N-type currents in a variety of central and peripheral neurons. omega-Aga-IVA blocked a substantial

Presynaptic calcium channels are crucial elements of neuronal excitation-secretion coupling. In mammalian brain, they have been difficult to characterize because most presynaptic terminals are too small to probe with electrodes, and available pharmacological tools such as dihydropyridines and omega-conotoxin are
