Voltage-dependent calcium channels 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, and gene expression. Calcium channels are multisubunit complexes composed of alpha-1, beta, alpha-2/delta, and gamma subunits. The channel activity is directed by the pore-forming alpha-1 subunit, whereas the others act as auxiliary subunits regulating this activity. The distinctive properties of the calcium channel types are related primarily to the expression of a variety of alpha-1 isoforms, namely alpha-1A, B, C, D, E, and S. This gene encodes the alpha-1D subunit. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]
GeneCards Summary for CACNA1D Gene
CACNA1D (Calcium Channel, Voltage-Dependent, L Type, Alpha 1D Subunit) is a Protein Coding gene. Diseases associated with CACNA1D include sinoatrial node dysfunction and deafness and primary aldosteronism, seizures, and neurologic abnormalities. Among its related pathways are MAPK signaling pathway and L1CAM interactions. GO annotations related to this gene include voltage-gated calcium channel activity and alpha-actinin binding. An important paralog of this gene is SCN1A.
UniProtKB/Swiss-Prot for CACNA1D Gene
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-1D 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).
Voltage-gated calcium channels (CaV) are present in the membrane of most excitable cells and mediate calcium influx in response to depolarisation. They regulate intracellular processes such as contraction, secretion, neurotransmission and gene expression. Voltage-gated calcium channels are formed from four or five distinct subunits; the alpha-subunit is the largest subunit and incorporates the voltage sensor, conduction pore and gating apparatus. Using pharmacological and electrophysiological techniques, at least 6 types of voltage-gated channels have been identified: L, N, P, Q, R and T, which are grouped into three families. Cav1.x are high-voltage-activated dihydropyridine-sensitive (L-type), Cav2.x are high-voltage-activated dihydropyridine-insensitive (N-, P- Q- and R-types) and Cav3.x are low-voltage-activated channels (T-type).
