Functioni

Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1A gives rise to P and/or Q-type calcium currents. P/Q-type calcium channels belong to the 'high-voltage activated' (HVA) group and are blocked by the funnel toxin (Ftx) and by the omega-agatoxin-IVA (omega-Aga-IVA). They are however insensitive to dihydropyridines (DHP), and omega-conotoxin-GVIA (omega-CTx-GVIA).

Involvement in diseasei

Defects in Cacna1a are the cause of a delayed-onset, recessive neurological disorder seen in tottering (tg) mutants, resulting in ataxia, motor seizures and behavioral absence seizures resembling petit mal epilepsy (or absence epilepsy) in humans. There are two more alleles, leaner (tg(lA)), that is characterized by severe ataxia and frequent death past weaning, but no motor seizures; and rolling Nagoya (tg(rol)), that presents an intermediary phenotype, the ataxia being somewhat more severe that with tg, but without motors seizures. Selective degeneration of cerebellar Purkinje cells has been shown for all these types of mutants. Selective degeneration of cerebellar Purkinje cells has been shown for all these types of mutants.

Tissue specificityi

Brain specific; mainly found in the cerebellum, olfactory bulb, cerebral cortex, hippocampus, and inferior colliculus. In the hippocampus, expression occurs in pyramidal and granule neurons, as well as in interneurons. Purkinje cells contain predominantly P-type VSCC, the Q-type being a prominent calcium current in cerebellar granule cells.

Interactioni

Subunit structurei

Voltage-dependent calcium channels are multisubunit complexes, consisting of alpha-1, alpha-2, beta and delta subunits in a 1:1:1:1 ratio. The channel activity is directed by the pore-forming and voltage-sensitive alpha-1 subunit. In many cases, this subunit is sufficient to generate voltage-sensitive calcium channel activity. The auxiliary subunits beta and alpha-2/delta linked by a disulfide bridge regulate the channel activity. Interacts with CABP1 (By similarity).By similarity

Domaini

Each of the four internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
