Calcium channel, voltage-dependent, L type, alpha 1C subunit (also known as Cav1.2) is a protein that in humans is encoded by the CACNA1C gene.[1] Cav1.2 is a subunit of L-type voltage-dependent calcium channel.[2]

Structure and function

This gene encodes an alpha-1 subunit of a voltage-dependent calcium channel. Calcium channels mediate the influx of calcium ions (Ca2+) into the cell upon membrane polarization (see membrane potential and calcium in biology).[3]

The alpha-1 subunit consists of 24 transmembrane segments and forms the pore through which ions pass into the cell. The calcium channel consists of a complex of alpha-1, alpha-2/delta and beta subunits in a 1:1:1 ratio. The S3-S4 linkers of Cav1.2 determine the gating phenotype and modulated gating kinetics of the channel.[4] Cav1.2 is widely expressed in the smooth muscle, pancreatic cells, fibroblasts, and neurons.[5][6] However, it is particularly important and well known for its expression in the heart where it mediates L-type currents, which causes calcium-induced calcium release from the ER Stores via ryanodine receptors. It depolarizes at -30mV and helps define the shape of the action potential in cardiac and smooth muscle.[4] The protein encoded by this gene binds to and is inhibited by dihydropyridine.[7] In the arteries of the brain, high levels of calcium in mitochondria elevates activity of nuclear factor kappa B NF-κB and transcription of CACNA1c and functional Cav1.2 expression increases.[8] Cav1.2 also regulates levels of osteoprotegerin.[9]

CaV1.2 is inhibited by the action of STIM1.[10]

Regulation

The activity of CaV1.2 channels is tightly regulated by the Ca2+ signals they produce. An increase in intracellular Ca2+ concentration implicated in Cav1.2 facilitation, a form of positive feedback called Ca2+-dependent facilitation, that amplifies Ca2+ influx. In addition, increasing influx intracellular Ca2+ concentration has implicated to exert the opposite effect Ca2+ dependent inactivation.[11] These activation and inactivation mechanisms both involve Ca2+ binding to calmodulin (CaM) in the IQ domain in the C-terminal tail of these channels.[12] Cav1.2 channels are arranged in cluster of eight, on average, in the cell membrane. When calcium ions bind to calmodulin, which in turn binds to a Cav1.2 channel, it allows the Cav1.2 channels within a cluster to interact with each other.[13] This results in channels working cooperatively when they open at the same time to allow more calcium ions to enter and then close together to allow the cell to relax.[13]

Due to simplicity only two Calcium channels are shown to depict clustering. When depolarization occurs, calcium ions flow through the channel and some bind to Calmodulin. The Calcium/Calmodulin binding to the C-terminal pre-IQ domain of the Cav1.2 channel promotes interaction between channels that are beside each other.

Clinical significance

Mutation in the CACNA1C gene, the single-nucleotide polymorphism located in the third intron of the Cav1.2 gene,[14] are associated with a variant of Long QT syndrome called Timothy's syndrome[15] and also with Brugada syndrome.[16] Large-scale genetic analyses have shown the possibility that CACNA1C is associated with bipolar disorder [17] and subsequently also with schizophrenia.[18][19][20] Also, a CACNA1C risk allele has been associated to a disruption in brain connectivity in patients with bipolar disorder, while not or only to a minor degree, in their unaffected relatives or healthy controls.[21]
