General annotation (Comments)

Function	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-1F gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, and by omega-agatoxin-IIIA (omega-Aga-IIIA). They are however insensitive to omega-conotoxin-GVIA (omega-CTx-GVIA) and omega-agatoxin-IVA (omega-Aga-IVA).
Subunit structure	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 (via IQ domain) with CABP4; in a calcium independent manner By similarity.
Subcellular location	Membrane; Multi-pass membrane protein.
Tissue specificity	Expression in skeletal muscle and retina. Ref.3
Domain	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.
Involvement in disease	Congenital stationary night blindness 2A (CSNB2A) [MIM:300071]: A non-progressive retinal disorder characterized by impaired night vision, often associated with nystagmus and myopia. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.1 Ref.2 Ref.6 Ref.7 Ref.8 Ref.9 Cone-rod dystrophy, X-linked 3 (CORDX3) [MIM:300476]: An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11 Aaland island eye disease (AIED) [MIM:300600]: A retinal disease characterized by a combination of fundus hypopigmentation, decreased visual acuity due to foveal hypoplasia, nystagmus, astigmatism, protan color vision defect, myopia, and defective dark adaptation. Except for progression of axial myopia, the disease can be considered to be a stationary condition. Electroretinography reveals abnormalities in both photopic and scotopic functions. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.12
Sequence similarities	Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. CACNA1F subfamily. [View classification]
Sequence caution	The sequence AAB92359.1 differs from that shown. Reason: Erroneous gene model prediction.
