Automated description from the Alliance of Genome Resources (Release 4.0)
Enables voltage-gated calcium channel activity. Acts upstream of or within several processes, including extraocular skeletal muscle development; myotube differentiation; and skeletal muscle adaptation. Located in T-tubule and sarcoplasmic reticulum. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and skeletal musculature. Used to study hypokalemic periodic paralysis. Human ortholog(s) of this gene implicated in hypokalemic periodic paralysis and malignant hyperthermia. Orthologous to human CACNA1S (calcium voltage-gated channel subunit alpha1 S).
