Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables calcium ion binding activity. Involved in several processes, including regulation of membrane repolarization; regulation of metal ion transport; and sarcomere organization. Acts upstream of or within regulation of cardiac muscle contraction by regulation of the release of sequestered calcium ion. Located in Z disc and sarcoplasmic reticulum lumen. Part of junctional membrane complex. Is expressed in several structures, including cardiovascular system; diaphragm; eye; male reproductive system; and skeletal muscle. Used to study catecholaminergic polymorphic ventricular tachycardia 2. Human ortholog(s) of this gene implicated in catecholaminergic polymorphic ventricular tachycardia 2. Orthologous to human CASQ2 (calsequestrin 2).
