CACNA1S Pore-forming, alpha-1S subunit of the voltage-gated calcium channel that gives rise to L-type calcium currents in skeletal muscle. Calcium channels containing the alpha-1S subunit play an important role in excitation-contraction coupling in skeletal muscle via their interaction with RYR1, which triggers Ca(2+) release from the sarcplasmic reticulum and ultimately results in muscle contraction. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. CACNA1S subfamily. Skeletal muscle specific. Note: This description may include information from UniProtKB.
