Summaries for CASQ2 Gene

Entrez Gene Summary for CASQ2 Gene

  • The protein encoded by this gene specifies the cardiac muscle family member of the calsequestrin family. Calsequestrin is localized to the sarcoplasmic reticulum in cardiac and slow skeletal muscle cells. The protein is a calcium binding protein that stores calcium for muscle function. Mutations in this gene cause stress-induced polymorphic ventricular tachycardia, also referred to as catecholaminergic polymorphic ventricular tachycardia 2 (CPVT2), a disease characterized by bidirectional ventricular tachycardia that may lead to cardiac arrest. [provided by RefSeq, Jul 2008]

GeneCards Summary for CASQ2 Gene

CASQ2 (Calsequestrin 2) is a Protein Coding gene. Diseases associated with CASQ2 include Ventricular Tachycardia, Catecholaminergic Polymorphic, 2 and Catecholaminergic Polymorphic Ventricular Tachycardia. Among its related pathways are Antiarrhythmic Pathway, Pharmacodynamics and Myometrial Relaxation and Contraction Pathways. GO annotations related to this gene include calcium ion binding and calcium-dependent protein binding. An important paralog of this gene is CASQ1.

UniProtKB/Swiss-Prot for CASQ2 Gene

  • Calsequestrin is a high-capacity, moderate affinity, calcium-binding protein and thus acts as an internal calcium store in muscle. Calcium ions are bound by clusters of acidic residues at the protein surface, especially at the interface between subunits. Can bind around 60 Ca(2+) ions. Regulates the release of lumenal Ca(2+) via the calcium release channel RYR2; this plays an important role in triggering muscle contraction. Plays a role in excitation-contraction coupling in the heart and in regulating the rate of heart beats.
