Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) 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 hindlimb musculature. Used to study hypokalemic periodic paralysis. Human ortholog(s) of this gene implicated in congenital myopathy 18; hypokalemic periodic paralysis; and malignant hyperthermia. Orthologous to human CACNA1S (calcium voltage-gated channel subunit alpha1 S). PHENOTYPE: Homozygous mutants show edema and failure of myoblast differentiation by day 13 of embryonic development and die perinatally. All muscles degenerate and additional secondary anomalies of the skeleton, short jaw, and cleft palate are seen. [provided by MGI curators] |
