Voltage-dependent L-type calcium channel subunit alpha-1S (CACNA1S) Recombinant Protein | CACNA1S recombinant protein
Recombinant Chicken Voltage-dependent L-type calcium channel subunit alpha-1S (CACNA1S)
NCBI and Uniprot Product Information
Uniprot Description
Function: 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
By similarity.
Subunit structure: Multisubunit complex consisting of alpha-1, alpha-2, beta and delta subunits in a 1:1:1:1 ratio. The channel activity is directed by the pore-forming and voltage-sensitive alpha-1 subunit. In many cases, this subunit is sufficient to generate voltage-sensitive calcium channel activity. The auxiliary subunits beta and alpha-2/delta linked by a disulfide bridge regulate the channel activity. An additional gamma subunit is present only in skeletal muscle L-type channel
By similarity.
Subcellular location: Membrane; Multi-pass membrane protein.
Domain: Each of the four internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.The loop between repeats II and III interacts with the ryanodine receptor, and is therefore important for calcium release from the endoplasmic reticulum necessary for muscle contraction
By similarity.
Post-translational modification: Phosphorylation by PKA stimulates the calcium channel function
By similarity.
Sequence similarities: Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. CACNA1S subfamily. [View classification]
