Description: 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-1S 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). Calcium channels containing the alpha-1S subunit play an important role in excitation-contraction coupling in skeletal muscle. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. Tissue specificity: Skeletal muscle specific. Defects in CACNA1S are a cause of periodic paralysis hypokalemic (HOKPP); also designated HYPOPP. HOKPP is an autosomal dominant disorder manifested by episodic flaccid generalized muscle weakness associated with falls of serum potassium levels. Defects in CACNA1S are the cause of malignant hyperthermia susceptibility 5 (MHS5); an autosomal dominant disorder that is potentially lethal in susceptible individuals on exposure to commonly used inhalational anesthetics and depolarizing muscle relaxants. Also known as: Voltage-dependent L-type calcium channel subunit alpha-1S, Voltage-gated calcium channel subunit alpha Cav1.1, Calcium channel, L type, alpha-1 polypeptide, isoform 3, skeletal muscle, CACH1, CACN1, CACNL1A3, CAC1S, Cav1.1.

Specificity: Appears to be specific for CACNA1S.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 2000 is recommended. The optimal dilution should be determined by the end user. Not tested in other applications.

Purity: whole serum

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
