Target Background

Function
CACNA1C antibody, biotin conjugated, targets the pore-forming, alpha-1C subunit of the voltage-gated calcium channel responsible for generating L-type calcium currents. It mediates calcium ion influx into the cytoplasm, triggering calcium release from the sarcoplasm. This process plays a critical role in excitation-contraction coupling within the heart, impacting heart development and rhythm regulation. Additionally, CACNA1C is essential for smooth muscle cell contraction in blood vessels and the intestine, contributing to normal blood pressure regulation via its influence on arterial smooth muscle cells. Long-lasting (L-type) calcium channels are classified as part of the 'high-voltage activated' (HVA) group (Probable).

Beyond its cardiovascular functions, CACNA1C also serves as a receptor for Influenzavirus. Its sialylated form, when expressed on lung tissues, may play a critical role in facilitating viral entry.

  2. This study demonstrates that CaV1.2 moves in vesicular structures with circular and tubular shapes, exhibiting diverse intracellular and submembrane trafficking patterns. Both microtubules and actin filaments are required for the dynamic movement of CaV1.2 vesicles. These vesicles undergo constitutive homotypic fusion and fission events that sustain CaV1.2 clustering, channel activity, and cooperative gating. PMID: 29959960

The CC genotype of rs10848683 may be a risk factor for LAA stroke under recessive models. Haplotypes of rs229961-rs215976-rs216008-rs10848683 in CACAN1C also showed increased risk of LAA stroke. PMID: 29683785

  6. This study is the first to suggest the involvement of the novel missense CACNA1C c.1786G>A and TTN c.49415G>A variants in the inheritance of symptomatic bradycardia and the development of sick sinus syndrome. PMID: 29568937
  7. MYH7-V878A and CACNA1C-A1594V mutations were detected in a Chinese family with hypertrophic cardiomyopathy.

  11. Results demonstrate that estrogen upregulates cardiac L-type Ca(2+) and sodium-calcium exchange in women through genomic mechanisms. These mechanisms account for sex differences in Ca(2+) handling and spatial heterogeneities of repolarization due to base-apex heterogeneities of Cav1.2alpha and NCX1. By analogy with rabbit studies, these effects account for human sex-difference in arrhythmia risk. PMID: 28807015
