CC -!- FUNCTION: Voltage-sensitive calcium channels (VSCC) mediate the entry
CC of calcium ions into excitable cells and are also involved in a variety
CC of calcium-dependent processes, including muscle contraction, hormone
CC or neurotransmitter release, gene expression, cell motility, cell
CC division and cell death. The isoform alpha-1D gives rise to L-type
CC calcium currents. Long-lasting (L-type) calcium channels belong to the
CC 'high-voltage activated' (HVA) group. They are blocked by
CC dihydropyridines (DHP), phenylalkylamines, and by benzothiazepines.
CC {ECO:0000269|PubMed:16354915}.
CC -!- SUBUNIT: Voltage-dependent calcium channels are multisubunit complexes,
CC consisting of alpha-1, alpha-2, beta and delta subunits in a 1:1:1:1
CC ratio. The channel activity is directed by the pore-forming and
CC voltage-sensitive alpha-1 subunit. In many cases, this subunit is
CC sufficient to generate voltage-sensitive calcium channel activity. The
CC auxiliary subunits beta and alpha-2/delta linked by a disulfide bridge
CC regulate the channel activity. Interacts (via IQ domain) with CABP1 and
CC CABP4 in a calcium independent manner. Interacts with RIMBP2 (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q99246-2; Sequence=Displayed;
CC Name=2; Synonyms=Cav1.3(1a);
CC IsoId=Q99246-3; Sequence=VSP_027091, VSP_027092;
CC Name=3; Synonyms=Cav1.3(1b);
CC IsoId=Q99246-4; Sequence=VSP_027090, VSP_027091, VSP_027092;
CC -!- TISSUE SPECIFICITY: Expressed in the inner hair cells (IHC) of the
CC cochlea. {ECO:0000269|PubMed:16354915}.
CC -!- DEVELOPMENTAL STAGE: Isoform 2 and isoform 3 are expressed in heart at
CC 12.5 dpc (at protein level). Expressed in the heart at 9.5, 12.5 and
CC 15.5 dpc. Isoform 2 and isoform 3 are expressed in heart at 9.5 and
CC 12.5 dpc. {ECO:0000269|PubMed:12900400}.
CC -!- INDUCTION: Up-regulated in CACNA1C knockout mice.
CC {ECO:0000269|PubMed:12900400}.
CC -!- DOMAIN: Each of the four internal repeats contains five hydrophobic
CC transmembrane segments (S1, S2, S3, S5, S6) and one positively charged
CC transmembrane segment (S4). S4 segments probably represent the voltage-
CC sensor and are characterized by a series of positively charged amino
CC acids at every third position.
CC -!- DISRUPTION PHENOTYPE: deafness, bradycardia and diabetic traits.
CC {ECO:0000269|PubMed:10929716, ECO:0000269|PubMed:11581302,
CC ECO:0000269|PubMed:12700358}.
CC -!- SIMILARITY: Belongs to the calcium channel alpha-1 subunit (TC
CC 1.A.1.11) family. CACNA1D subfamily. {ECO:0000305}.
